+# TypeScript and JavaScript Coding Style Guide
+
+# Overview
+
+## Purpose
+
+This guide is applicable to the scenario where TypeScript and JavaScript are used during OpenHarmony application development.
+
+Based on the technical features of language engines and OpenHarmony, as well as industry standards and practices, this guide provides coding guide for improving code standardization, security, and performance.
+
+## Source
+
+This guide is developed based on the *JavaScript Coding Style Guide* [1]. It integrates the technical features of OpenHarmony without violating industry rules, including ESLint and TSC configuration.
+
+The correct and incorrect examples, marked with **@typescript-eslint**, in ESLint rules come from ESLint Rules [2].
+
+## Document Structure
+
+- [OpenHarmony Application Environment Restrictions](#openharmony-application-environment-restrictions)
+
+  All the restrictions provided in this section are raised for security purposes and therefore are mandatory.
+
+- Programming language features: [Declaration and Initialization](#declaration-and-initialization), [Data Types](#data-types), [Operation and Expressions](#operation-and-expressions), [Functions](#functions), [Classes and Objects](#classes-and-objects), and [Exceptions](#exceptions), [Async Functions](#async-functions), and [Types](#types).
+
+## Conventions
+
+**Rule**: a convention that must be complied with
+
+**Recommendation**: a convention that must be taken into consideration
+
+It is necessary to understand the reason for each rule or recommendation and try to comply with them.
+
+# OpenHarmony Application Environment Restrictions
+
+## Use Strict Mode
+
+**[Category] Rule**
+
+**[Description]**
+
+Strict mode is a way to opt in to a restricted variant of JavaScript, thereby implicitly opting out of sloppy mode.
+
+1. Strict mode eliminates some JavaScript silent errors by throwing errors.
+1. Strict mode fixes defects that make it difficult for JavaScript engines to perform optimizations. Sometimes, the same code can run faster in strict mode than in non-strict mode.
+1. Strict mode prohibits some syntax that may be defined in future versions of ECMAScript.
+
+**Note: Currently, only TypeScript or JavaScript code in strict mode is supported on OpenHarmony ArkCompiler.**
+
+## Do Not Use eval()
+
+**[Category] Rule**
+
+**[Description]**
+
+Using **eval()** causes code disorder and poor readability.
+
+**[Incorrect Example]**
+
+```javascript
+console.log (eval ({ a:2 })); // Output [object Object].
+console.log(eval('"a" + 2')); // Output 'a2'.
+console.log(eval('{a: 2}')); // Output 2.
+console.log(eval('let value = 1 + 1;'); // Output undefined.
+```
+
+## Do Not Use with() {}
+
+**[Category] Rule**
+
+**[Description]**
+
+Using **with()** makes the code semantically unclear because the object of **with()** may conflict with local variables, changing the original semantics.
+
+**[Incorrect Example]**
+
+```javascript
+const foo = { x: 5 };
+with (foo) {
+  let x = 3;
+  console.log(x);  // x = 3
+}
+console.log(foo.x);  // x = 3
+```
+
+## Do Not Dynamically Create Functions
+
+**[Category] Rule**
+
+**[Description]**
+
+A function can be defined in three ways: declaration, constructor, and expression. No matter which means is used, the function created is an instance of the **Function** object and inherits all default or custom methods and attributes of the **Function** object. Defining a function by using a constructor is similar to the using of **eval()**. The constructor accepts any string as the function body, causing security vulnerabilities.
+
+**[Incorrect Example]**
+
+```javascript
+let add = new Function('a','b','return a + b');
+// The function constructor can have only one parameter, which can be any string.
+let dd = new Function('alert("hello")');
+```
+
+**[Correct Example]**
+
+```javascript
+// Function declaration.
+function add(a,b){
+  return a+b;
+}
+// Function expression.
+let add = function(a,b){
+  return a+b;
+}
+```
+
+# Declaration and Initialization
+
+## Use const or let Instead of var to Declare Variables
+
+**[Category] Rule**
+
+**[Description]**
+
+ECMAScript 6 allows the use of the **let** and **const** keywords to declare variables in the block scope instead of the function scope. The block scope is commonly used in many programming languages. It is helpful in preventing errors. Use **const** to define read-only variables, and use **let** to define other variables.
+
+**[Incorrect Example]**
+
+```javascript
+var number = 1;
+var count = 1;
+if (isOK) {
+  count += 1;
+}
+```
+
+**[Correct Example]**
+
+```javascript
+const number = 1;
+let count = 1;
+if (isOK) {
+  count += 1;
+}
+```
+
+# Data Types
+
+## Do Not Omit 0s Before and After the Decimal Point of a Floating-Point Number
+
+**[Category] Rule**
+
+**[Description]**
+
+In JavaScript, a floating-point number must contain a decimal point, but no digit is required before or after the decimal point. This makes it difficult to distinguish between the decimal point and the dot operator. For this reason, you must use a digit before and after the decimal point for a floating-point number in OpenHarmony code.
+
+**[Incorrect Example]**
+
+```javascript
+const num = .5;
+const num = 2.;
+const num = -.7;
+```
+
+**[Correct Example]**
+
+```javascript
+const num = 0.5;
+const num = 2.0;
+const num = -0.7;
+```
+
+## Use isNaN() to Check Whether a Variable Is NaN
+
+**[Category] Rule**
+
+**[Description]**
+
+In JavaScript, NaN is a particular value of a numeric data type. It represents a non-numeric value in the double-precision 64-bit format, as defined in the IEEE floating-point standard.
+NaN is unique in JavaScript because it is not equal to any value, including itself. Therefore, the result of comparison with NaN is confusing, as the values of **NaN !== NaN** and **NaN != NaN** are both **true**.
+Therefore, you must use **Number.isNaN()** or the global **isNaN()** function to check whether a variable is NaN.
+
+**[Incorrect Example]**
+
+```javascript
+if (foo == NaN) {
+  // ...
+}
+if (foo != NaN) {
+  // ...
+}
+```
+
+**[Correct Example]**
+
+```javascript
+if (isNaN(foo)) {
+  // ...
+}
+if (!isNaN(foo)) {
+  // ...
+}
+```
+
+## Do Not Use == or === to Check Whether Floating-Point Numbers Are Equal
+
+**[Category] Rule**
+
+**[Description]**
+
+Due to the precision problem, mathematically equal numbers may not be equal in floating-point arithmetic. Therefore, the equality operators **==** and **===** cannot be used to check whether floating-point numbers are equal.
+
+**[Incorrect Example]**
+
+```javascript
+0.1 + 0.2 == 0.3; // false
+0.1 + 0.2 === 0.3; // false
+```
+
+**[Correct Example]**
+
+```javascript
+const EPSILON = 1e-6;
+const num1 = 0.1;
+const num2 = 0.2;
+const sum = 0.3;
+if(Math.abs(num1 + num2 - sum) < EPSILON) {
+  ...
+}
+```
+
+## Do Not Define or Use Non-numeric Attributes (Except Length) for Arrays
+
+**[Category] Rule**
+
+**[Description]**
+
+In JavaScript, an array is an object, which can be added with attributes. To facilitate processing and avoid errors, use an array to store only a group of ordered data, that is, data with continuous indexes. If attributes must be added, use **Map** or **Object** instead.
+
+**[Incorrect Example]**
+
+```javascript
+const myHash = [];
+myHash['key1'] = 'val1';
+myHash['key2'] = 'val2';
+myHash[0] = '222';
+for (const key in myHash) {
+  // The value of key is 0, key1, and key2.
+  console.log(key);
+}
+console.log(myHash.length); // The array length is 1.
+```
+
+**[Correct Example]**
+
+Use Map and Object for non-numeric attributes.
+
+```javascript
+const map = new Map();
+map.set('key1', 'val1');
+map.set('key2', 'val2');
+for(const [key, value] of map) {
+  console.log('Attribute:' + key +', value: '+ value);
+}
+```
+
+## Preferentially Use Array Object Methods for Array Traversal
+
+**[Category] Rule**
+
+**[Description]**
+
+To traverse an array, preferentially use the methods provided by **Array**, such as **forEach()**, **map()**, **every()**, **filter()**, **find()**, **findIndex()**, **reduce()**, and **some()**.
+Do not use **for in** to traverse an array.
+
+**[Incorrect Example]**
+
+```javascript
+const numbers = [1, 2, 3, 4, 5];
+let sum = 0;
+// Use for in to traverse the array.
+for (const num in numbers) {
+  console.log(num);
+  sum += num;
+}
+// Use for to traverse an existing array to generate a new array.
+const increasedByOne = [];
+for (let i = 0; i < numbers.length; i++) {
+  increasedByOne.push(numbers[i] + 1);
+}
+```
+
+**[Correct Example]**
+
+```javascript
+const numbers = [1, 2, 3, 4, 5];
+// Use for of to traverse the array and obtain the sum.
+let sum = 0;
+for (const num of numbers) {
+  sum += num;
+}
+// Use forEach to traverse the array and obtain the sum.
+let sum = 0;
+numbers.forEach(num => sum += num);
+// Better: Use the reduce method to obtain the sum.
+const sum = numbers.reduce((total, num) => total + num, 0);
+// Use forEach to traverse an existing array to generate a new array.
+const increasedByOne = [];
+numbers.forEach(num => increasedByOne.push(num + 1));
+// Better: Use the map method.
+const increasedByOne = numbers.map(num => num + 1);
+```
+
+# Operation and Expressions
+
+## Use === and !==, Instead of == or !=, to Check Whether the Operands Are Equal
+
+**[Category] Rule**
+
+**[Description]**
+
+In JavaScript, type conversion is automatically performed when the **==** operator is used for equality judgment. For example, the values of **[] == false**, **[] == ![]**, and **3 == '03'** are **true**. For higher efficiency, use **===** in comparison when the type is determined.
+
+**[Incorrect Example]**
+
+```javascript
+age == bee
+foo == true
+bananas != 1
+value == undefined
+typeof foo == 'undefined'
+'hello' != 'world'
+0 == 0
+true == true
+```
+
+**[Correct Example]**
+
+```javascript
+age === bee
+foo === true
+bananas !== 1
+value === undefined
+typeof foo === 'undefined'
+'hello' !== 'world'
+0 === 0
+true === true
+```
+
+**[Exceptions]**
+
+```javascript
+// Use the following to determine whether an object is null:
+obj == null
+obj != null
+```
+
+## Do Not Assign Values in Control Conditional Expressions
+
+**[Category] Rule**
+
+**[Description]**
+
+Control conditional expressions are usually used in conditional statements such as **if**, **while**, **for**, and **?:**.
+Assigning values in this type of expression often leads to unexpected behavior and poor code readability.
+
+**[Incorrect Example]**
+
+```javascript
+// It is difficult to understand the value assignment in the control conditional expression. 
+if (isFoo = false) {
+  ...
+}
+```
+
+**[Correct Example]**
+
+```javascript
+const isFoo = someBoolean; // Assign a value above and directly use it in the if statement.
+if (isFoo) {
+  ...
+}
+```
+
+# Functions
+
+## Use the Same Return Statement
+
+**[Category] Rule**
+
+**[Description]**
+
+Unlike statically typed languages that force a function to return a value of a specified type, JavaScript allows different code paths in a function to return different types of values.
+
+JavaScript returns **undefined** in the following cases:
+
+1. The **return** statement is not executed before the exit.
+1. The **return** statement is executed, but no value is explicitly assigned.
+1. The **return undefined** statement is executed.
+1. The **return void** statement is executed, followed by an expression (for example, a function call).
+1. The **return** statement is executed, followed by another expression equivalent to **undefined**.
+
+In a function (especially in a larger function), if any code path explicitly returns a value but the other code paths do not explicitly return a value, this may be a coding error. Therefore, use the same **return** statement in a function.
+
+**[Incorrect Example]**
+
+```javascript
+function doSomething(condition) {
+  if (condition) {
+    ...
+    return true;
+  } else {
+    ...
+    return;
+  }
+}
+function doSomething(condition) {
+  if (condition) {
+    ...
+    return true;
+  }
+}
+```
+
+**[Correct Example]**
+
+```javascript
+// Ensure that all paths return values in the same way.
+function doSomething(condition) {
+  if (condition) {
+    ...
+    return true;
+  } else {
+    ...
+    return false;
+  }
+}
+
+function doSomething(condition) {
+  if (condition) {
+    ...
+    return true;
+  }
+  ...
+  return false;
+}
+```
+
+## Use rest Instead of arguments
+
+**[Category] Rule**
+
+**[Description]**
+
+The **rest** parameter is an array, and all array methods, such as **sort**, **map**, **forEach**, and **pop**, can be directly used on it. **arguments** is a class array. Therefore, use the **rest** syntax instead of **arguments**. In addition, place the **rest** parameter as the last parameter in the list.
+
+**[Incorrect Example]**
+
+```javascript
+function concatenateAll() {
+  // arguments is a class array, and the join method can be used only after arguments is converted to a real array.
+  const args = Array.prototype.slice.call(arguments);   
+  return args.join('');
+}
+```
+
+**[Correct Example]**
+
+```javascript
+function concatenateAll(...args) {
+  return args.join('');
+}
+```
+
+## Do Not Assign this to a Variable; Use this in a Scope
+
+**[Category] Rule**
+
+**[Description]**
+
+Arrow functions provide a simpler syntax. **this** in an arrow function points to the object when it is defined. Assigning **this** to a variable is confusing.
+
+**[Incorrect Example]**
+
+```javascript
+function foo() {
+  const self = this;
+  return function() {
+    console.log(self);
+  };
+}
+```
+
+**[Correct Example]**
+
+```javascript
+function foo() {
+  return () => {
+    console.log(this);
+  };
+}
+```
+
+For details, see [@typescript-eslint/no-this-alias](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-this-alias.md).
+
+The description of ESLint is stricter. Therefore, do not assign **this** to a variable in any case.
+
+# Classes and Objects
+
+## Use Dots to Access Object Attributes and [] to Access Computed Attributes
+
+**[Category] Rule**
+
+**[Description]**
+
+In JavaScript, you can use dots (**foo.bar**) or square brackets (**foo['bar']**) to access attributes. The use of dots is preferred because it is more readable, concise, and more suitable for JavaScript compression.
+
+**[Correct Example]**
+
+```javascript
+const name = obj.name;
+const key = getKeyFromDB();
+const prop = obj[key]; // Use [] only when the attribute name is a variable.
+```
+
+## Do Not Modify the Prototype of a Built-in Object or Add Methods to the Prototype
+
+**[Category] Rule**
+
+**[Description]**
+
+As a set of public interfaces, built-in objects have conventional behavior modes. Any modification to the prototype of a built-in object may damage the semantics. Therefore, never modify the prototype of a built-in object, or add methods to the prototype.
+
+**[Incorrect Example]**
+
+```javascript
+Array.prototype.indexOf = function () {
+  return -1;
+}
+// Used in other places.
+const arr = [1, 1, 1, 1, 1, 2, 1, 1, 1];
+console.log (arr.indexOf(2)); // Output -1.
+```
+
+## Do Not Delete the Computed Attributes of an Object
+
+**[Category] Rule**
+
+**[Description]**
+
+The delete operation changes the layout of an object. Deleting the computed attributes of an object is a dangerous behavior. It greatly restricts the runtime optimization and affects the execution performance.
+
+You are advised not to delete any attribute of an object. If necessary, use **map** and **set**.
+
+**[Incorrect Example]**
+
+```javascript
+// Can be replaced with the constant equivalents, such as container.aaa
+delete container['aaa'];
+
+// Dynamic, difficult-to-reason-about lookups
+const name = 'name';
+delete container[name];
+delete container[name.toUpperCase()];
+```
+
+**[Correct Example]**
+
+```javascript
+// The code affects the optimization performance to some extent, but it is better than deleting the computed attributes.
+delete container.aaa;
+
+delete container[7];
+```
+
+For details, see [@typescript-eslint/no-dynamic-delete](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-dynamic-delete.md).
+
+# Exceptions
+
+## Do Not Use return, break, continue, or throw to End the Finally Block Abnormally
+
+**[Category] Rule**
+
+**[Description]**
+
+In the finally block, if the **return**, **break**, **continue**, or **throw** statement is directly used or the exception that occurs during the method calling is not handled, the finally block ends abnormally. Such a block affects the throwing of exceptions in the **try** or **catch** block, or even the return value of the method. Therefore, you must ensure that the finally block ends normally.
+
+**[Incorrect Example]**
+
+```javascript
+function foo() {
+  try {
+    ...
+    return 1;
+  } catch(err) {
+    ...
+    return 2;
+  } finally {
+    return 3;
+ }
+}
+```
+
+**[Correct Example]**
+
+```javascript
+function foo() {
+  try {
+    ...
+    return 1;
+  } catch(err) {
+    ...
+    return 2;
+  } finally {
+    console.log('XXX!');
+  }
+}
+```
+
+# Async Functions
+
+## Use return await Only When Necessary
+
+**[Category] Rule**
+
+**[Description]**
+
+The return value of an async function is always encapsulated in **Promise.resolve**. The **return await** statement does not actually do anything, but adds time before **Promise.resolve** or **reject**. Therefore, use **return await** only in the **try** or **catch** statement to capture errors of another promise-based function.
+
+**[Incorrect Example]**
+
+```javascript
+async function foo() {
+  return await bar();
+}
+```
+
+**[Correct Example]**
+
+```javascript
+async function foo() {
+  return bar();
+}
+async function foo() {
+  await bar();
+  return;
+}
+async function foo() {
+  const baz = await bar();
+  return baz;
+}
+async function foo() {
+  try {
+    return await bar();
+  } catch (error) {
+    // here can be executed, go on
+  }
+}
+```
+
+## Do Not Wait for a Non-thenable Value
+
+**[Category] Rule**
+
+**[Description]**
+
+**await** converts a non-thenable value to a promise that has been processed normally and waits for the processing result. In this case, the use of **await** affects the code performance.
+
+**[Incorrect Example]**
+
+```javascript
+async function f3() {
+  const y = await 20;
+  console.log(y); // 20
+}
+
+f3();
+console.log(30);
+
+// output
+// 30
+// 20
+```
+
+**[Correct Example]**
+
+```javascript
+async function f3() {
+  const y = 20;
+  console.log(y); // 20
+}
+
+f3();
+console.log(30);
+
+// output
+// 20
+// 30
+```
+
+For details, see [@typescript-eslint/await-thenable](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/await-thenable.md).
+
+# Types
+
+## Forcibly Mark null and undefined as Independent Types
+
+**[Category] Rule**
+
+**[Description]**
+
+Marking **null** and **undefined** as independent types improves code security and avoids null pointer exceptions.
+
+**[Incorrect Example]**
+
+```javascript
+let userName: string;
+userName = 'hello';
+userName = undefined;
+```
+
+**[Correct Example]**
+
+```javascript
+let userName: string | undefined;
+userName = 'hello';
+userName = undefined;
+```
+
+## Explicitly Declare the Return Value Types of Functions and Class Methods
+
+**[Category] Rule**
+
+**[Description]**
+
+Explicitly declare the return value type to ensure that the return value is assigned to the variable of the correct type. In addition, the explicit declaration ensures that **undefined** is not assigned to a variable when there is no return value.
+
+**[Incorrect Example]**
+
+```javascript
+// When there is no return value, the return value type is not declared as void.
+function test() {
+  return;
+}
+// The return value type is not declared as number.
+function fn() {
+  return 1;
+};
+// The return value type is not declared as string.
+let arrowFn = () => 'test';
+class Test {
+  // When there is no return value, the return value type is not declared as void.
+  method() {
+    return;
+  }
+}
+```
+
+**[Correct Example]**
+
+```javascript
+// When there is no return value, explicitly declare the return value type as void.
+function test(): void {
+  return;
+}

+  // When there is no return value, explicitly declare the return value type as void.
+  method(): void {

+
+## Use Consistent Export Types
+
+**[Category] Rule**
+
+**[Description]**
+
+To export a type, write the type to export and the objects to export separately.
+
+**[Incorrect Example]**
+
+```javascript
+interface ButtonProps {
+  onClick: () => void;
+}
+class Button implements ButtonProps {
+  onClick() {
+    console.log('button!');
+  }
+}
+export { Button, ButtonProps };
+```
+
+**[Correct Example]**
+
+```javascript
+interface ButtonProps {
+  onClick: () => void;
+}
+class Button implements ButtonProps {
+  onClick() {
+    console.log('button!');
+  }
+}
+export { Button };
+export type { ButtonProps };
+```
+
+For details, see [@typescript-eslint/consistent-type-exports](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/consistent-type-exports.md).
+
+## Use Consistent Import Types
+
+**[Category] Rule**
+
+**[Description]**
+
+To import a type, write the type to import and the objects to import separately.
+
+**[Incorrect Example]**
+
+```javascript
+import { Foo } from 'Foo';
+import Bar from 'Bar';
+type T = Foo;
+const x: Bar = 1;
+```
+
+**[Correct Example]**
+
+```javascript
+import type { Foo } from 'Foo';
+import type Bar from 'Bar';
+type T = Foo;
+const x: Bar = 1;
+```
+
+For details, see [@typescript-eslint/consistent-type-imports](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/consistent-type-imports.md).
+
+## Do Not Use any
+
+**[Category] Rule**
+
+**[Description]**
+
+If the **any** type is used, all type checks during compilation are ignored. This behavior is not necessary and does not meet expectations. If the type is unknown, use **unknown**.
+If the introduced third-party component does not use TypeScript or does not provide the TypeScript type declaration, you can use **any** to declare the related third-party component objects.
+
+## Do Not Define the any Type
+
+**[Category] Rule**
+
+**[Description]**
+
+Do not define the **any** type. This restriction makes types as clear as possible in TypeScript and helps the runtime optimization.
+
+**[Incorrect Example]**
+
+```javascript
+const age: any = 'seventeen';
+function greet(): any {}
+function greet(param: Array<any>): string {}
+```
+
+**[Correct Example]**
+
+```javascript
+const age: number = 17;
+function greet(): string {}
+function greet(param: Array<string>): string {}
+```
+
+For details, see [@typescript-eslint/no-explicit-any](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-explicit-any.md).
+
+## Do Not Pass In any as a Parameter
+
+**[Category] Rule**
+
+**[Incorrect Example]**
+
+```javascript
+declare function foo(arg1: string, arg2: number, arg3: string): void;
+
+const anyTyped = 1 as any;
+
+foo(...anyTyped);
+foo(anyTyped, 1, 'a');
+
+const tuple1 = ['a', anyTyped, 'b'] as const;
+foo(...tuple1);
+```
+
+**[Correct Example]**
+
+```javascript
+declare function foo(arg1: string, arg2: number, arg3: string): void;
+
+foo('a', 1, 'b');
+
+const tuple1 = ['a', 1, 'b'] as const;
+foo(...tuple1);
+```
+
+For details, see [@typescript-eslint/no-unsafe-argument](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-unsafe-argument.md).
+
+## Do Not Use any in Value Assignment
+
+**[Category] Rule**
+
+**[Incorrect Example]**
+
+```javascript
+const x = 1 as any,
+
+const x: Set<string> = new Set<any>();
+```
+
+**[Correct Example]**
+
+```javascript
+const x = 1;
+
+const x: Set<string> = new Set<string>();
+```
+
+For details, see [@typescript-eslint/no-unsafe-assignment](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-unsafe-assignment.md).
+
+## Do Not Call a Variable with the any Type
+
+**[Category] Rule**
+
+**[Incorrect Example]**
+
+```javascript
+declare const anyVar: any;
+declare const nestedAny: { prop: any };
+
+anyVar();
+anyVar.a.b();
+
+nestedAny.prop();
+nestedAny.prop['a']();
+```
+
+**[Correct Example]**
+
+```javascript
+declare const typedVar: () => void;
+declare const typedNested: { prop: { a: () => void } };
+
+typedVar();
+typedNested.prop.a();
+```
+
+For details, see [@typescript-eslint/no-unsafe-call](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-unsafe-call.md).
+
+## Do Not Access Members of an Object with the any Type
+
+**[Category] Rule**
+
+**[Incorrect Example]**
+
+```markup
+declare const anyVar: any;
+declare const nestedAny: { prop: any };
+
+anyVar.a;
+anyVar.a.b;
+
+nestedAny.prop.a;
+nestedAny.prop['a'];
+```
+
+**[Correct Example]**
+
+```javascript
+declare const properlyTyped: { prop: { a: string } };

+## Do Not Declare the Return Value Type of a Function as any or any[]
+
+**[Category] Rule**
+
+**[Incorrect Example]**

-# OpenHarmony Part Design Guide
+# OpenHarmony Component Design Guide
 
-## About This Document
+## Basic Concepts
 
-For easy software design and management, OpenHarmony decouples software from physical components, parts, and modules. A **component** can be independently deployed and reused at the binary level. A **part** can be independently developed, built, and tested. A **module** can be reused at the code level.
+For easy software design and management, OpenHarmony decouples software from images, components (named components originally), and modules. Their relationship is shown below.
 
-OpenHarmony abstracts system capabilities as parts, so you can assemble and configure these parts to customize an OS for different devices.
+![](figures/Component-Module.png)
 
-## Part Definition
+### Component Definition
 
-A part is the basic unit of system capabilities. Divided based on source code, every part has independent files and directories, and can be instantiated into libraries or executable files on different devices.
+OpenHarmony abstracts system capabilities as components, so you can customize OSs for different devices by assembling and configuring these components.
 
-## Part Division
+A component is the basic unit of system capabilities. Divided based on source code, every component has independent files and directories, and can be instantiated into libraries or executable files on different devices.
 
-Observe the following rules for part classification:
+The introduction of components is to enable a set of OS code to support a variety of product forms, thereby solving the problem of hardware and product fragmentation in different industries and improving the device development efficiency.
 
-- A part must have an independent code directory for compiling libraries or executable files.
+![](figures/Component-Definition.png)
 
-- A part must be able to be independently deployed in the small system or standard system. Optional parts can be tailored without causing system exceptions.
+## Component Design
 
-- Functions of a part must be able to be independently tested and verified.
+### Component Classification Rules
 
-A part always belongs to a specific subsystem. A subsystem is a logical concept and consists of specific parts.
+When developing a new function that is optional and can be tailored, add a component, rather than a module. In addition, observe the following rules:
 
-Note the following:
+- A component must have an independent code directory for compiling libraries or executable files.
+- A component must be able to be independently deployed in the small system or standard system. Optional functions can be tailored without causing system exceptions.
+- A component must be able to be independently tested and verified.
 
-- External APIs provided by a part must be the same regardless of whether the configurable features of the part are configured.
+### **Rules and Recommendations**
 
-- Dependent third-party open source software libraries and parts that provide basic capabilities are called **dependent parts**, which must be deployed with other parts.
+Comply with the following rules and recommendations during component design:
 
-- If a part can be split into smaller functional modules and provide APIs for applications, these modules are called **child parts**, which must be deployed with the parent part. A child part depends on a parent part, but a parent part does not depend on a child part.
+**Rule 1.1** Components must be developed individually to ensure decoupling and independence.
 
-## Basic Principles
+**Rule 1.2** A common component should not depend on a specific chip, development board, or product form, except for a component related to drivers and kernels.
 
-Comply with the following rules and recommendations during parts design and development:
+**Rule 1.3** All components in the minimum system component set are mandatory. They should not depend on an optional component outside the minimum system component set.
 
-**Rule 1.1** Parts must be developed individually to ensure decoupling and independence.
+> For details about the definition of the minimum system and the minimum system component set, see **PCS** in [OpenHarmony Product Compatibility Specifications](https://www.openharmony.cn/certification/document/pcs).
 
-**Rule 1.2** Parts must be managed in a decentralized manner. The dependency between parts must be simple, clear, and reasonable.
+**Rule 1.4** New components must be reviewed by architects and designers in the respective domain.
 
-**Rule 1.3** Reverse dependency and cyclic dependency between parts are prohibited. Lower-layer parts must not depend on upper-layer parts.
+**Rule 1.5** Reverse dependency and cyclic dependency between components are prohibited. Lower-layer components must not depend on upper-layer components.
 
-**Rule 1.4** It is prohibited that the implementation of a part depends on a specific development board or product form.
+**Rule 1.6** Application APIs provided by a component must be stable and compatible with earlier versions. Deprecated APIs must be reclaimed as planned.
 
-**Rule 1.5** APIs provided by a part must be stable and compatible. Changes to released APIs are prohibited.
+**Rule 1.7** External APIs provided by a component must be the same regardless of whether the configurable features of the component are configured.
 
-**Rec 1.1** Parts should support automated build and verification.
+**Rule 1.8** The component name must reflect the key function of a component and must be globally unique in the system. The name can contain a maximum of 63 characters and must be in the unix_like style, where only lowercase letters separated by underscores (\_) are used.
 
-## Naming Rules
+**Rule 1.9** The component repository must be named in the format of <Subsystem\>\_<Component\>. For example, the repository name of the storage service component in the file management subsystem is **filemanagement\_storage\_service**. The repository name can contain a maximum of 100 characters.
 
-#### **Part Name**
-
-The name must reflect the key function of a part and must be globally unique in the system. It can contain a maximum of 63 characters and must be in the unix\_like style, where only lowercase letters separated by underscores (\_) are used.
-
-#### **Repository Name**
-
-The part repository is named in the format of <Subsystem\>\_<Part\>. For example, the repository name of the storage service part in the file management subsystem is **filemanagement\_storage\_service**. The repository name can contain a maximum of 100 characters.
-
-> Note:
+> **NOTE**
 >
-> 1. In principle, there is a one-to-one mapping between parts and repositories. In some cases, multiple parts can share a repository, but they must have independent directories.

-## Adding, Deleting, or Modifying Parts
+**Rec 1.1** Components should support automated build and verification.
+
+### System Capabilities
+
+System capabilities are provided by components. A system capability can be bound to one or more APIs. System capabilities function as a bridge between device development and application development. The differences in devices assembled with various components are represented by different system capabilities. In other words, the APIs that can be used vary according to the device in use. The figure below shows how system capabilities are used in the entire development process.
+
+![](figures/Component-SysCap.png)
+
+1. An application developer uses the normalized SDK that supports multiple devices to develop an application. The SDK contains a full set of system capabilities (optional and mandatory) and corresponding APIs.
+
+2. A device developer assembles optional components and adds private components to form the system capability set of a device.
+
+3. The system capability set is automatically written to the device during compilation and packaging.
+
+4. A Product Compatibility ID (PCID) is automatically generated during device compilation. When developing an application for a specific device, the application developer imports the PCID to DevEco Studio to obtain the system capability set of the device during development.
 
-The addition, deletion, and modification of parts must be reviewed by the architecture SIG and [related domain SIGs](https://gitee.com/openharmony/community/blob/master/sig/sigs_subsystem_list.md). The review process is as follows:
+5. A Required Product Compatibility ID (RPCID), a set of system capabilities required by the application, is automatically generated during application compilation and packaging.
 
-1. Prepare the following part attribute review form.
+6. When distributing an application, the application market matches the application's RPCID against the device's PCID. It distributes the application to that device only if the application's RPCID is within the device's PCID.
 
-Table 1 Part attribute review form
+7. In the ability continuation scenario, the system capabilities are synchronized between devices.
 
-| Part Attribute | Description |
-| ------------ | ------------------------------------------------------------ |
-| Part name | The name must reflect the key function of a part and must be globally unique in the system. The name can contain a maximum of 63 characters and must be in the unix\_like style, where only lowercase letters separated by underscores (\_) are used. |
-| Subsystem | Subsystem to which the part belongs. |
-| Function description | Brief description of the functions of the part in one or two sentences. |
-| Configurable features | Features that can be configured externally. |
-| Applicable systems | Mini system, small system, standard system, or their combinations. |
-| Source code directory | Root directory of the source code of the part. |
-| ROM          | ROM baseline value of the part. |
-| RAM          | RAM baseline value of the part. |
-| Dependencies | Parts and open source software on which the part depends. |
+8. In the installation-free scenario, the system capabilities of a device can be queried on the cloud.
 
+#### Using System Capabilities During Application Development
 
-2. Send an email to the architecture SIG (dev@openharmony.io) and the [related domain SIG leaders](https://gitee.com/openharmony/community/blob/master/sig/sigs_subsystem_list.md) for review. Use "Application for Adding/Deleting/Modifying OpenHarmony Parts" as the email subject, and include the filled-in **Table 1 Part Attribute Review Form** in the email body.
+An application developer can call the **CanIUse** API to query the system capabilities of a device at runtime. The code snippet is as follows:
+
+```javascript
+import geolocation from '@ohos.geolocation'
+
+const isLocationAvailable = canIUse('SystemCapability.Location.Location');
+if (isLocationAvailable) {
+    geolocation.getCurrentLocation((location) => {
+        console.log(location.latitude, location.longitue);
+    });
+} else {
+    console.log('Location not by this device.')
+}
+```
+
+The SDK defines the system capability set for typical device types. If a device type is selected during application development and the API called exceeds the range supported by the mandatory system capabilities of the device type, DevEco Studio displays a message indicating that the API is not supported by the device and the application compilation will fail.
+
+#### Defining System Capabilities During Device Development
+
+There is a one-to-one relationship between components and system capabilities, and the APIs mapped to different system capabilities do not overlap. A system capability must be named in the format of SystemCapability.Category. Feature.Subfeature (optional), for example, **SystemCapability.Media.Camera** and **SystemCapability.Media.Camera.Front**. Generally, a subfeature is implemented by an independent component. This component depends on a component that provides the basic feature, and therefore the dependent component must also be assembled into the product.
+
+1. Declare the system capability in the **bundle.json** file of the component. The code snippet is as follows:
+
+   ```json
+   {
+     ...
+     "component": {
+       "name": "camera",                              # Component name.
+       "syscap": [ "SystemCapability.Media.Camera" ]  # System capability of the component.
+     },
+     ...
+   }
+   ```
+
+2. Declare the system capability attribute of the API in the corresponding .d.ts file for binding. The code snippet is as follows:
+
+   ```js
+   /**
+    * @name camera
+    * @syscap SystemCapability.Media.Camera
+    * @ since 9
+    */
+   declare namespace camera {
+       ...
+   }
+   ```
+
+### Component Review
+
+The addition, modification (function or interface changes), and deletion of components must be reviewed by the architecture SIG and [related domain SIGs](https://gitee.com/openharmony/community/tree/master/sig). The review process is as follows:
+
+1. Prepare the following component attribute review form.
+
+   Table 1 Component attribute review form
+
+   | Component Attribute    | Description                                                        |
+   | ------------ | ------------------------------------------------------------ |
+   | Component name    | The name must reflect the key function of a component and must be globally unique in the system. The name can contain a maximum of 63 characters and must be in the unix\_like style, where only lowercase letters separated by underscores (\_) are used.|
+   | Subsystem      | Subsystem to which the component belongs.                                          |
+   | Function description    | Brief description of the functions of the component in one or two sentences.                         |
+   | Configurable features  | Features that can be configured externally.                                      |
+   | SysCap       | System capability, for example, **SystemCapability.Media.Camera** or **SystemCapability.Media.Camera.Front**.|
+   | Applicable systems| Mini system, small system, standard system, or their combinations.    |
+   | Source code directory    | Root directory of the source code of the component.                                          |
+   | ROM          | ROM baseline value of the component.                                       |
+   | RAM          | RAM baseline value of the component.                                       |
+   | Dependencies        | Components and open source software on which the component depends.                              |
+
+
+2. Send an email to the architecture SIG (dev@openharmony.io) and the [related domain SIG leaders](https://gitee.com/openharmony/community/tree/master/sig) for review. Use "Applying for Adding/Modifying/Deleting OpenHarmony Components" as the email subject, and include the filled-in **Table 1 Component Attribute Review Form** in the email body.
+
+   > For deleted components, provide the plan for stopping component maintenance. Exercise caution when deleting or modifying components and evaluate the impact on existing versions.
+
+3. After the review is passed, create a component repository and modify the manifest according to [SIG Management Regulations](https://gitee.com/openharmony/community/blob/master/sig/README_EN.md). After the SIG is incubated, incorporate it into the main code library of OpenHarmony.
+
+## Component Development
+
+After the component passes the review, the component name, repository, and source code path are determined. You can perform component development as follows:
+
+### Adding a Description File
+
+In the development state, create a **bundle.json** file in the root directory of the component. The file contains the component name, compilation, test, system capability, features, and internal interfaces. For details about the fields, see [Description File](../device-dev/subsystems/subsys-build-component-building-rules.md#description-file). The code snippet is as follows:
+
+```json
+{
+    "name": "@ohos/my_component",
+    "description": "my first component",
+    "version": "4.0",
+    "license": "Apache License 2.0",
+    "publicAs": "code-segment",
+    "segment": {
+        "destPath": "my_domain/my_subsystem/my_component"
+    },
+    "component": {
+        "name": "my_component",
+        "subsystem": "my_subsystem",
+        "syscap": [
+            "SystemCapability.MySubsystem.MyComponent"
+        ],
+        "build": {
+            "moudles": [
+                "//my_domain/my_subsystem/my_component/my_module:my_module"
+            ],
+            "inner_api": [
+                "name": "//my_domain/my_subsystem/my_component/my_module:inner_api",
+                "header_base": "//my_domain/my_subsystem/my_component/interfaces/inner_api/my_module"
+            ],
+            "test": [
+                "//my_domain/my_subsystem/my_component:unit_test"
+            ]
+        }
+    }
+}
+```
+
+**inner_api** is an interface declared by the component for dependency between components within the system. The dependency must be specified in **external_deps**. The following is an example:
+
+```c
+ohos_executable("other_component") {
+    ...
+    external_deps = [ "my_module:inner_api" ]
+}
+```
+
+### Adding a Compilation Script
+
+In the **bundle.json** file, **build:modules** provides the component compilation entry. The following is an example of the compilation script of the **my_module** module in the dynamic library:
+
+```c
+ohos_shared_library("my_module") {
+  sources = [ ... ]
+  ...
+  external_deps = [ ... ]
+    
+  part_name = "my_component"
+  subsystem_name = "my_subsystem"
+}
+```
 
-> Note: 
+The component compilation script must comply with component-based requirements. For details, see [Component Building Specifications](../device-dev/subsystems/subsys-build-component-building-rules.md#component-building-specifications).
+
+### Compilation Verification
+
+After adding the description file and compilation script of the component, compile the code source to develop the functions of the component. To enable the compilation of a component, configure the component in the product configuration file. The following is an example:
+
+```json
+{
+  "product_name": "my_product",
+  "device_company": "my_device_company",
+  "target_cpu": "arm",
+  ...
+  "subsystems": [
+    {
+      "subsystem": "my_subsystem",
+      "components": [
+        {
+          "component": "my_component"
+        }
+      ]
+    },  
+  ...
+  ]
+}
+```
+
+The following code snippet is used to compile a component separately:
+
+```c
+./build.sh --product-name my_product --build-target my_domain/my_subsystem/my_component/my_module:my_module
+```
+
+Upload the compilation products and test cases of the component to the device to verify the functions.
+
+Full compilation can also be used to verify a new component. For details, see [Adding and Compiling Components](../device-dev/subsystems/subsys-build-component.md#adding-and-building-a-component).
+
+## Assembling Components
+
+The product configuration file ***vendor*/*{company}*/*{product}*/config.json** can be used to assemble a product form based on the component and feature dimensions. It allows device developers to quickly build a product without intrusively modifying OpenHarmony source code. The product configuration includes the product name, development board, subsystems, and components. The following is an example:
+
+```json
+{
+  "product_name": "my_product",
+  "device_company": "my_device_company",
+  "target_cpu": "arm64",
+  "subsystems": [
+    {
+      "subsystem": "my_subsystem",
+      "components": [
+        {
+          "component": "my_component",
+          "features": []
+        }
+      ]
+    },
+    ...
+   ]
+}
+```
+
+The compilation command is **./build.sh --product-name my_product**.
+
+### Determining Whether a Component Is Required
+
+A component set can be configured for a product based on hardware and product functions. For example, NFC-related components are not configured on a device that does not need to provide the NFC feature.
+
+> **NOTE**
+>
+> 1. The minimum system component set must be configured by default.
 >
-> For modified parts, provide a before and after comparison of the part attributes. For deleted parts, provide the plan for stopping part maintenance. Exercise caution when deleting or modifying parts and evaluate the impact on existing versions.
+> 2. A component and its dependent components must be configured together. Otherwise, the compilation fails.
+
+### Configuring Features
+
+#### During Compilation
+
+A feature in the **bundle.json** file of a component is the compilation state option declared by the component. It can be of the Boolean, numeric, or string type. The feature in the product configuration file can be changed to the default value provided by the component. For example, the screen saver feature of power management is disabled by default. You can enable it in the product as follows:
+
+```json
+{
+  {
+    "subsystem": "powermgr",
+    "components": [
+      { "component": "powermgr", "features":[ "powermgr_screensaver_enable = true" ] }
+    ]
+  }
+}
+```
+
+For details about the feature configuration, see [Feature](../device-dev/subsystems/subsys-build-feature.md).
+
+#### Runtime
+
+For complex components, system parameters can be read or custom configuration files can be used during runtime to load different features, thereby meeting diverse product requirements. With feature configuration at the runtime, a component needs to be compiled only once. For different products, you only need to modify system parameters or configuration files during assembly and then create images.
+
+### Inheritance
+
+The product configuration file can inherit the component set through the **inherit** field. Currently, OpenHarmony provides two types of components: minimum system component set and typical product form set, which are defined in the **productdefine/common/base** and **productdefine/common/inherit** directories, respectively. The following is an example of inheriting the minimum system component set:
+
+```json
+{
+    "inherit": [ "productdefine/common/base/standard_system.json" ],
+}
+```
 
-3. After the review is passed, create a part repository and modify the manifest according to [SIG Management Regulations](https://gitee.com/openharmony/community/blob/master/sig/README_EN.md). After the SIG is incubated, incorporate it into the main code library of OpenHarmony.
+Inheritance can simplify product configuration and improve efficiency.

+# Interactive Tool User Guide
+
+## Introduction
+
+You can use Bindgen and CXX to implement the interaction between Rust and C/C++. Bindgen enables Rust to call C by converting C interfaces into Rust interfaces. CXX implement interaction between C++ and Rust by generating bindings between C interfaces and Rust interfaces.
+
+![bindgen_and_cxx_tools](./figures/bindgen_and_cxx_tools.png)
+
+## Using Bindgen
+
+### Procedure
+The following example shows how to use Bindgen to implement invocation of C by Rust.
+
+1. In the header file **lib.h**, define two interfaces **FuncAAddB** and **SayHello** in C. The **FuncAAddB** interface calculates the sum of two numbers, and the **SayHello** interface prints strings.
+
+   ```c
+   #ifndef BUILD_RUST_TESTS_BINDGEN_TEST_LIB_H_
+   #define BUILD_RUST_TESTS_BINDGEN_TEST_LIB_H_
+   #include <stdint.h>
+   #include "build/rust/tests/test_bindgen_test/test_for_hello_world/lib2.h"
+   
+   uint32_t FuncAAddB(uint32_t a, uint32_t b);
+   void SayHello(const char *message);
+   
+   #endif  //  BUILD_RUST_TESTS_BINDGEN_TEST_LIB_H_
+   ```
+
+
+2. Add the implementation of the two interfaces to **lib.c**.
+
+   ```c
+   #include "build/rust/tests/test_bindgen_test/test_for_hello_world/lib.h"
+   #include <stdint.h>
+   #include <stdio.h>
+
+   void SayHello(const char *message)
+   {
+       printf("This is a test for bindgen hello world:\n");
+       printf("%s\n", message);
+   }
+
+   uint32_t FuncAAddB(uint32_t a, uint32_t b)
+   {
+       printf("This is a test for bindgen of a + b:\n");
+       return a + b;
+   }
+   ```
+
+3. Create the **main.rs** file to call C interfaces through c_ffi using Rust. Note that insecure interfaces called by Rust must be encapsulated by using **unsafe**.
+
+   ```rust
+   //!  bindgen test for hello world
+   #![allow(clippy::approx_constant)]
+   mod c_ffi {
+       #![allow(dead_code)]
+       #![allow(non_upper_case_globals)]
+       #![allow(non_camel_case_types)]
+       include!(env!("BINDGEN_RS_FILE"));
+   }
+   /// pub fn add_two_numbers_in_c
+   pub fn add_two_numbers_in_c(a: u32, b: u32) -> u32 {
+       unsafe { c_ffi::FuncAAddB(a, b) }
+   }
+
+   use std::ffi::c_char;
+   use std::ffi::CString;
+
+   /// fn main()
+   fn main() {
+       println!("{} + {} = {}", 3, 7, add_two_numbers_in_c(3, 7));
+       let c_str = CString::new("This is a message from C").unwrap();
+       let c_world: *const c_char = c_str.as_ptr() as *const c_char;
+       unsafe {
+           c_ffi::SayHello(c_world);
+       }
+   }
+
+   ```
+
+4. Create the **BUILD.gn** file to define the dependency of the Rust module on the C module.
+
+   ```GN
+   import("//build/ohos.gni")
+
+   ohos_shared_library("c_lib") {
+     sources = [ "lib.c" ]
+     defines = [ "COMPONENT_IMPLEMENTATION" ]
+   }
+
+   rust_bindgen("c_lib_bindgen") {
+     header = "lib.h"
+   }
+
+   ohos_rust_executable("bindgen_test") {
+     deps = [ ":c_lib" ]
+     deps += [ ":c_lib_bindgen" ]
+     sources = [ "main.rs" ]
+     bindgen_output = get_target_outputs(":c_lib_bindgen")
+     inputs = bindgen_output
+     rustenv = [ "BINDGEN_RS_FILE=" + rebase_path(bindgen_output[0]) ]
+     crate_root = "main.rs"
+   }
+   ```
+
+**Verification**
+
+![bindgen_test](./figures/bindgen_test.png)
+
+
+## Using CXX
+
+### Calling Rust Interfaces by C++
+
+1. In the Rust **lib.rs** file, add the C++ interfaces to be called in **mod ffi**, and add the interfaces in **extern "Rust"** to expose them to C++. 
+
+   ```rust
+   //! #[cxx::bridge]
+   #[cxx::bridge]
+   mod ffi{
+       #![allow(dead_code)]
+       #[derive(Clone, Debug, PartialEq, Eq, PartialOrd, Ord)]
+       struct Shared {
+           z: usize,
+       }
+       extern "Rust"{
+           fn print_message_in_rust();
+           fn r_return_primitive() -> usize;
+           fn r_return_shared() -> Shared;
+           fn r_return_rust_string() -> String;
+           fn r_return_sum(_: usize, _: usize) -> usize;
+       }
+   }
+
+   fn print_message_in_rust(){
+       println!("Here is a test for cpp call Rust.");
+   }
+   fn r_return_shared() -> ffi::Shared {
+       println!("Here is a message from Rust,test for ffi::Shared:");
+       ffi::Shared { z: 1996 }
+   }
+   fn r_return_primitive() -> usize {
+       println!("Here is a message from Rust,test for usize:");
+       1997
+   }
+   fn r_return_rust_string() -> String {
+       println!("Here is a message from Rust,test for String");
+       "Hello World!".to_owned()
+   }
+   fn r_return_sum(n1: usize, n2: usize) -> usize {
+       println!("Here is a message from Rust,test for {} + {} is:",n1 ,n2);
+       n1 + n2
+   }
+
+   ```
+
+2. Include **lib.rs.h** (converted from **lib.rs** by the CXX tool) in C++ code.
+
+   ```c++
+   #include <iostream>
+   #include "build/rust/tests/test_cxx/src/lib.rs.h"
+
+   int main(int argc, const char* argv[])
+   {
+       int a = 2021;
+       int b = 4;
+       print_message_in_rust();
+       std::cout << r_return_primitive() << std::endl;
+       std::cout << r_return_shared().z << std::endl;
+       std::cout << std::string(r_return_rust_string()) << std::endl;
+       std::cout << r_return_sum(a, b) << std::endl;
+       return 0;
+   }
+   ```
+
+3. Create the **BUILD.gn** file. The underlying rust_cxx calls the CXX tool to convert the **lib.rs** file into **lib.rs.h** and **lib.rs.cc**. **ohos_rust_static_ffi** implements compilation of the Rust source code, and **ohos_executable** implements compilation of the C++ code.
+
+   ```
+   import("//build/ohos.gni")
+   import("//build/templates/rust/rust_cxx.gni")
+
+   rust_cxx("test_cxx_exe_gen") {
+       sources = [ "src/lib.rs" ]
+   }
+
+   ohos_rust_static_ffi("test_cxx_examp_rust") {
+       sources = [ "src/lib.rs" ]
+       deps = [ "//build/rust:cxx_rustdeps" ]
+   }
+
+   ohos_executable("test_cxx_exe") {
+       sources = [ "main.cpp" ]
+       sources += get_target_outputs(":test_cxx_exe_gen")
+
+       include_dirs = [ "${target_gen_dir}" ]
+       deps = [
+       ":test_cxx_examp_rust",
+       ":test_cxx_exe_gen",
+       "//build/rust:cxx_cppdeps",
+       ]
+   }
+   ```
+
+**Verification**
+![cpp_call_rust](./figures/cpp_call_rust.png)
+
+
+### Calling C++ by Rust
+
+1. Create the header file **client_blobstore.h**.
+
+   ```c++
+   #ifndef BUILD_RUST_TESTS_CLIENT_BLOBSTORE_H
+   #define BUILD_RUST_TESTS_CLIENT_BLOBSTORE_H
+   #include <memory>
+   #include "third_party/rust/cxx/include/cxx.h"
+
+   namespace nsp_org {
+   namespace nsp_blobstore {
+   struct MultiBufs;
+   struct Metadata_Blob;
+
+   class client_blobstore {
+   public:
+       client_blobstore();
+       uint64_t put_buf(MultiBufs &buf) const;
+       void add_tag(uint64_t blobid, rust::Str add_tag) const;
+       Metadata_Blob get_metadata(uint64_t blobid) const;
+
+   private:
+       class impl;
+       std::shared_ptr<impl> impl;
+   };
+
+   std::unique_ptr<client_blobstore> blobstore_client_new();
+   } // namespace nsp_blobstore
+   } // namespace nsp_org
+   #endif
+   ```
+
+2. Create the **client_blobstore.cpp** file.
+
+   ```c++
+   #include <algorithm>
+   #include <functional>
+   #include <set>
+   #include <string>
+   #include <unordered_map>
+   #include "src/main.rs.h"
+   #include "build/rust/tests/test_cxx_rust/include/client_blobstore.h"
+
+   namespace nsp_org {
+   namespace nsp_blobstore {
+   // Toy implementation of an in-memory nsp_blobstore.
+   //
+   // The real implementation of client_blobstore could be a large complex C++
+   // library.
+   class client_blobstore::impl {
+       friend client_blobstore;
+       using Blob = struct {
+           std::string data;
+           std::set<std::string> tags;
+       };
+       std::unordered_map<uint64_t, Blob> blobs;
+   };
+
+   client_blobstore::client_blobstore() : impl(new class client_blobstore::impl) {}
+
+   // Upload a new blob and return a blobid that serves as a handle to the blob.
+   uint64_t client_blobstore::put_buf(MultiBufs &buf) const
+   {
+       std::string contents;
+
+       // Traverse the caller's res_chunk iterator.
+       //
+       // In reality there might be sophisticated batching of chunks and/or parallel
+       // upload implemented by the nsp_blobstore's C++ client.
+       while (true) {
+           auto res_chunk = next_chunk(buf);
+           if (res_chunk.size() == 0) {
+           break;
+           }
+           contents.append(reinterpret_cast<const char *>(res_chunk.data()), res_chunk.size());
+       }
+
+       // Insert into map and provide caller the handle.
+       auto res = std::hash<std::string> {} (contents);
+       impl->blobs[res] = {std::move(contents), {}};
+       return res;
+   }
+
+   // Add add_tag to an existing blob.
+   void client_blobstore::add_tag(uint64_t blobid, rust::Str add_tag) const
+   {
+       impl->blobs[blobid].tags.emplace(add_tag);
+   }
+
+   // Retrieve get_metadata about a blob.
+   Metadata_Blob client_blobstore::get_metadata(uint64_t blobid) const
+   {
+       Metadata_Blob get_metadata {};
+       auto blob = impl->blobs.find(blobid);
+       if (blob != impl->blobs.end()) {
+           get_metadata.size = blob->second.data.size();
+           std::for_each(blob->second.tags.cbegin(), blob->second.tags.cend(),
+               [&](auto &t) { get_metadata.tags.emplace_back(t); });
+       }
+       return get_metadata;
+   }
+
+   std::unique_ptr<client_blobstore> blobstore_client_new()
+   {
+       return std::make_unique<client_blobstore>();
+   }
+   } // namespace nsp_blobstore
+   } // namespace nsp_org
+
+   ```
+
+3. In **ffi** of the **main.rs** file, use the macro **includes!** to import the header file **client_blobstore.h**. Then, the **main()** function of Rust can call the C++ interfaces in ffi mode.
+
+   ```rust
+   //! test_cxx_rust
+   #[cxx::bridge(namespace = "nsp_org::nsp_blobstore")]
+   mod ffi {
+       // Shared structs with fields visible to both languages.
+       struct Metadata_Blob {

+# Using Cargo2gn
+## Overview
+
+Rust uses Cargo as its build system and package manager. **Cargo.toml** is the manifest file of Cargo. It contains metadata such as the name, version, and dependencies for crates (packages) in Rust. 
+
+When used in OpenHarmony, **Cargo.toml** needs to be converted into **BUILD.gn** rules. cargo2gn is the tool that can achieve this purpose. It can convert one or more Rust libraries.
+
+##  Converting a Single Library
+1. Go to the directory of the rust library to be converted, for example, **bindgen**.
+
+    ```
+    cd openharmony/third_party/rust/bindgen
+    ```
+    
+2. Create the configuration file **cargo2gn.json**.
+
+    ```
+    {
+        "copy-out": true,
+        "run": true,
+        "add-workspace": true,
+        "cargo-bin": "/mnt/xxx/openharmony/prebuilts/rustc/linux-x86_64/current/bin"
+    }
+    ```
+    
+3. Run the following command to perform the conversion:
+   
+   ```
+   python /mnt/xxx/openharmony/build/scripts/cargo2gn.py --config cargo2gn.json
+   ```
+   
+   The conversion result is as follows:
+   
+   ```
+   import("//build/templates/rust/ohos_cargo_crate.gni")
+   
+   ohos_cargo_crate("lib") {

+       build_script_outputs = ["host-target.txt"]
+   }
+   ```
+   
+   
+
+##  Converting Multiple Libraries in Batches
+1. Go to the **rust** directory.
+   
+   ```
+   cd openharmony/third_party/rust
+   ```
+2. Add all the rust libraries to be converted to [workspace] in **Cargo.toml** in the **rust** directory.
+
+    ```
+    [workspace]
+    members = [
+        "aho-corasick",
+        "memchr",
+    ]
+    ```
+3. Perform steps 2 and 3 in section "Converting a Single Library".

+# Rust Module Configuration Rules and Guide
+
+## Introduction
+
+Rust is a static, strongly typed programming language. It has advantages such as secure memory management, high running performance, and native support for multi-thread development. Rust uses Cargo to create projects and compile and build Rust code.
+
+To integrate C/C++ code and improve the build speed, OpenHarmony uses Generate Ninja (GN) and Ninja as its build system. GN has simple and easy-to-use build language, and Ninja provides direct and efficient assembly-level build rules.
+
+To integrate Rust code and maximize the interaction between the C/C++ code used in OpenHarmony and Rust, OpenHarmony uses GN as a unified build tool to build Rust source code files (xxx.rs) and is added with features such as interoperability with C/C++, compile time lints, test, IDL conversion, third-party library integration, and IDE. In addition, the GN framework is extended to support automatic interface conversion, which greatly simplifying development.
+
+### Basic Concepts
+
+| Term | Description                                                        |
+| ----- | ------------------------------------------------------------ |
+| Cargo | Cargo is an official build tool used by Rust. It allows Rust projects to declare dependencies and ensures reproducible builds.|
+| crate | Crate is a unit that can be independently compiled.                               |
+| Lint| Lint is a code analysis tool used to flag programming errors, bugs, stylistic errors, and suspicious constructs. It performs extensive error analysis on programs.|
+
+
+
+## Configure Rules
+OpenHarmony provides a variety of GN templates for compiling Rust executables, dynamic libraries, and static libraries. The following table describes the templates.
+
+| GN Template                  | Description             | Output                                           |
+| ------------------------ | ----------------- | ----------------------------------------------- |
+| ohos_rust_executable     | Rust executable file.   | Rust executable file, without the file name extension.                       |
+| ohos_rust_shared_library | Rust dynamic library.       | Rust dylib dynamic library, with the default file name extension **.dylib.so**.            |
+| ohos_rust_static_library | Rust static library.       | Rust rlib static library, with the default file name extension **.rlib**.                 |
+| ohos_rust_proc_macro     | Rust proc_macro library.   | Rust proc_macro library, with the default file name extension **.so**.                |
+| ohos_rust_shared_ffi     | Rust Foreign Function Interface (FFI) dynamic library.   | Rust cdylib dynamic library, which is called by the C/C++ module. The default file name extension is **.so**.|
+| ohos_rust_static_ffi     | Rust FFI static library.   | Rust staticlib library, which is called by the C/C++ module. The default file name extension is **.a**.  |
+| ohos_rust_cargo_crate    | Third-party Cargo crate.| Third-party Rust crates, which support rlib, dylib, and bin.             |
+| ohos_rust_systemtest     | Rust system test cases. | Executable system test cases for Rust, without the file name extension.               |
+| ohos_rust_unittest       | Rust unit test cases. | Executable unit test cases for Rust, without the file name extension.               |
+
+
+
+## Configuration Guide
+The configuration of the Rust module is similar to that of the C/C++ module. For details, see [Module Configuration Rules](subsys-build-module.md). The following provides examples of using different Rust templates.
+### Configuring a Rust Static Library
+The following example shows how to use the **ohos_rust_executable** and **ohos_rust_static_library** templates to build a binary executable and a static rlib library, respectively. The executable depends on the static library. 
+
+The procedure is as follows:
+
+1. Create **build/rust/tests/test_rlib_crate/src/simple_printer.rs**.
+
+   ```rust
+   //! simple_printer
+   
+   /// struct RustLogMessage
+   
+   pub struct RustLogMessage {
+       /// i32: id
+       pub id: i32,
+       /// String: msg
+       pub msg: String,
+   }
+   
+   /// function rust_log_rlib
+   pub fn rust_log_rlib(msg: RustLogMessage) {
+       println!("id:{} message:{:?}", msg.id, msg.msg)
+   }
+   ```
+
+2. Create **build/rust/tests/test_rlib_crate/src/main.rs**.
+
+   ```rust
+   //! rlib_crate example for Rust.
+   
+   extern crate simple_printer_rlib;
+   
+   use simple_printer_rlib::rust_log_rlib;
+   use simple_printer_rlib::RustLogMessage;
+   
+   fn main() {
+       let msg: RustLogMessage = RustLogMessage {
+           id: 0,
+           msg: "string in rlib crate".to_string(),
+       };
+       rust_log_rlib(msg);
+   }
+   ```
+
+3. Configure the GN build script **build/rust/tests/test_rlib_crate/BUILD.gn**.
+
+   ```
+   import("//build/ohos.gni")
+   
+   ohos_rust_executable("test_rlib_crate") {
+     sources = [ "src/main.rs" ]
+     deps = [ ":simple_printer_rlib" ]
+   }
+   
+   ohos_rust_static_library("simple_printer_rlib") {
+     sources = [ "src/simple_printer.rs" ]
+     crate_name = "simple_printer_rlib"
+     crate_type = "rlib"
+     features = [ "std" ]
+   }
+   ```
+   
+4. Run the **BUILD.gn** to generate the build targets.
+
+   ![test_rlib_crate](./figures/test_rlib_crate.png)
+
+### Configuring a Third-Party Library
+The following example shows how to use the **ohos_rust_executable** and **ohos_rust_cargo_crate** templates to build a third-party static rlib library whose code contains a prebuilt file **build.rs**. 
+
+The procedure is as follows:
+
+1. Create **build/rust/tests/test_rlib_cargo_crate/crate/src/lib.rs**.
+
+   ```rust
+   include!(concat!(env!("OUT_DIR"), "/generated/generated.rs"));
+   
+   pub fn say_hello_from_crate() {
+       assert_eq!(run_some_generated_code(), 45);
+       #[cfg(is_new_rustc)]
+       println!("Is new rustc");
+       #[cfg(is_old_rustc)]
+       println!("Is old rustc");
+       #[cfg(is_ohos)]
+       println!("Is ohos");
+       #[cfg(is_mac)]
+       println!("Is darwin");
+       #[cfg(has_feature_a)]
+       println!("Has feature_a");
+       #[cfg(not(has_feature_a))]
+       panic!("Wasn't passed feature_a");
+       #[cfg(not(has_feature_b))]
+       #[cfg(test_a_and_b)]
+       panic!("feature_b wasn't passed");
+       #[cfg(has_feature_b)]
+       #[cfg(not(test_a_and_b))]
+       panic!("feature_b was passed");
+   }
+   
+   #[cfg(test)]
+   mod tests {
+       /// Test features are passed through from BUILD.gn correctly. This test is the target configuration.
+       #[test]
+       #[cfg(test_a_and_b)]
+       fn test_features_passed_target1() {
+           #[cfg(not(has_feature_a))]
+           panic!("feature a was not passed");
+           #[cfg(not(has_feature_b))]
+           panic!("feature b was not passed");
+       }
+   
+       #[test]
+       fn test_generated_code_works() {
+           assert_eq!(crate::run_some_generated_code(), 45);
+       }
+   }
+   ```
+
+2. Create **build/rust/tests/test_rlib_cargo_crate/crate/src/main.rs**.
+
+   ```rust
+   pub fn main() {
+       test_rlib_crate::say_hello_from_crate();

+   use std::process::Command;
+   use std::str::{self, FromStr};
+   
+   fn main() {
+       println!("cargo:rustc-cfg=build_script_ran");
+       let my_minor = match rustc_minor_version() {
+           Some(my_minor) => my_minor,
+           None => return,
+       };
+   
+       if my_minor >= 34 {
+           println!("cargo:rustc-cfg=is_new_rustc");
+       } else {
+           println!("cargo:rustc-cfg=is_old_rustc");
+       }
+   
+       let target = env::var("TARGET").unwrap();
+   
+       if target.contains("ohos") {
+           println!("cargo:rustc-cfg=is_ohos");
+       }
+       if target.contains("darwin") {
+           println!("cargo:rustc-cfg=is_mac");
+       }
+   
+       let feature_a = env::var_os("CARGO_FEATURE_MY_FEATURE_A").is_some();

+### Feature Examples
+
+#### Linking a C/C++ library in Rust Source Code
+By default, the dynamic library of the OpenHarmony C/C++ module is in the **.z.so** format. However, when the Rust **-l** command is executed, only the dynamic library in the **.so** format is linked by default. If a C/C++ dynamic library is used as the dependency, you need to add **output_extension = "so"** to the GN build script of the dynamic library to make the generated dynamic library be named with **.so** instead of **.z.so**.
+
+If a dynamic library is directly linked in the Rust source code, the dynamic library must be in **.so** format. In this case, use the dynamic library name without "lib". The following is an example of linking **libhilog.so** in the Rust source code.
+
+```rust
+#[link(name = "hilog")]
+```
+#### Using externs
+If a module depends on the binary rlib library, you can use the **externs** attribute.
+```
+executable("foo") {
+    sources = [ "main.rs" ]
+    externs = [{                    # Convert it to `--extern bar=path/to/bar.rlib` during the compilation.
+        crate_name = "bar"
+        path = "path/to/bar.rlib"
+    }]
+}
+```
+### Lint Rules
+The OpenHarmony framework supports two types of lints: rustc lints and Clippy lints. Each type of lint has three levels: openharmony (highest), vendor, and none (lowest).
+
+When configuring the Rust module, you can specify the lint level in **rustc_lints** or **clippy_lints**.
+If **rustc_lints** or **clippy_lints** is not configured in the module, the lint level is matched based on the module path. Different restrictions apply to the syntax specifications of Rust code in different directories. Therefore, you need to pay attention to the path of the module when configuring the Rust module to build in OpenHarmony.
+
+#### Levels of rustc Lints and Clippy Lints
+| **Lint Type**| **Module Attribute**| **Lint Level**| **Lint Level Flag**| **Lint Content**                                               |

+# Bundle Management Subsystem Changelog
+
+## cl.bundlemanager.1 Changed Underlying Capability by Not Decompressing the HAP During HAP Installation
+
+The HAP will no longer be decompressed during installation. After the installation is complete, only the HAP file exists in the installation directory. As a result, the application must use the standard resource management interface, rather than a combined path, to access a resource file.
+
+**Change Impact**<br>
+If the application uses a combined path to access a resource file, the access fails. It must use the resource management interface.
+
+**Key API/Component Changes**<br>
+No API or component change is involved.

-# 预置应用配置与安装指导
-
-预置应用是指随OpenHarmony系统出厂预置的应用。
-
-本文介绍开发者如何将一个非预置应用配置为预置应用，以及已有预置应用更新后如何重新安装。
-
-## 将非预置应用配置为预置应用。
-
-1. 确定预置应用支持的路径，可以通过下述命令查询。本文将以路径/system/etc/app/为例。
-
-```
-hdc_std param get const.cust.config_dir_layer
-```
-
-2. 在install_list.json中配置hap在设备上的路径。
-
-```
-hdc_std shell mount -o rw,renount /
-hdc_std file recv /system/etc/app/install_list.json .
-```
-
-3. 按照json中的配置方式，配置对应的字段。
-
-```
-{
-    "app_dir":"system/app/xxxx/yyyy",  // 设备上的hap路径，如果不存在，需要手动创建，并推送hap到此目录。
-    "removable":true // 是否支持卸载，false表示不可卸载，true表示可以卸载。
-}
-```
-
-4. 修改完成后，将install_list.json文件推送到设备上，并重启设备生效。
-
-```
-    hdc_std shell mount -o rw,remount /
-    hdc_std file send install_list.json /system/etc/app/install_list.json
-    hdc_std shell reboot
-```
-
-## 重新安装更新后的已有预置应用
-
-有两种方法。
-
-- 方法一：直接清空data，重启设备，应用会自动安装。
-
-```
-    hdc_std shell mount -o rw,remount / 
-    hdc_std shell rm /data/* -rf
-    hdc_std shell sync
-    hdc_std shell /system/bin/udevadm trigger
-    hdc_std shell reboot
-```
-- 方法二：如果该应用之前没有安装过，则可以执行下面命令后重启设备。
-
-```
-    hdc_std shell mount -o rw,remount /
-    hdc_std shell param set persist.bms.test-upgrade true
-    hdc_std shell reboot
-```
-
-如果应用之前已经安装过，这时继续推送新的hap到/system/app/的路径下，则需要保证应用的版本号，分为[Stage模型的版本号（versionCode）](../../application-dev/quick-start/app-configuration-file.md)，[FA模型的版本号（code）](../../application-dev/quick-start/app-structure.md#version对象内部结构)比之前的大。 这时执行方法二的命令，重启后应用同样可以正常安装。需要注意的是方法二命令，不需要反复执行， 重启之后依然生效。

-# 预置应用配置指南

-OpenHarmony支持在不同产品上对预置应用进行差异化配置，设备厂商可根据需要对预置应用进行配置。
+预置应用是指随设备出厂预置的应用。OpenHarmony支持在不同设备上对预置应用进行差异化配置，设备厂商可根据需要对与预置应用进行配置。
 
-此外，OpenHarmony根据GetCfgDirList获得系统支持的预置目录，如system、chipset、sys_prod、chip_prod；并且按照返回的顺序越靠后优先级越高，如chip_prod的优先级高于system的优先级。
+## 将应用配置为预置应用
 
-## 预置应用安装列表配置
+1. 在进行预置应用配置前，使用如下命令查询系统支持的预置目录。
+   
+   命令查询结果如system、chipset、sys_prod、chip_prod等，并且返回的顺序越靠后优先级越高，如chip_prod的优先级高于system的优先级。本文以路径/system/etc/app/为例。
 
-### 应用预置到系统中的配置步骤
+```
+hdc shell param get const.cust.config_dir_layer
+```
+
+2. 在install_list.json中配置hap在设备上的路径。
 
-1. 在预置目录下创建应用的名称作为应用目录
-2. 将应用预置到应用目录下，如 /system/app/Hiworld/entry.hap
-3. 添加应用目录到[install_list.json](https://gitee.com/openharmony/vendor_hihope/blob/master/rk3568/preinstall-config/install_list.json)，根据需求配置removable
+```
+hdc shell mount -o rw,remount /
+hdc file recv /system/etc/app/install_list.json .
+```
 
-### 示例
+3. 按照json中的配置方式，配置对应的字段。
 
 ```
 {
     "install_list" : [
         {
-            "app_dir" : "/system/app/Hiworld",
-            "removable" : false // 是否可卸载
+            "app_dir":"system/app/xxxx/yyyy",  // 设备上的hap路径，如果不存在，需要手动创建，并推送hap到此目录。
+            "removable":true // 是否支持卸载，false表示不可卸载，true表示可以卸载。
         }
     ]
 }
 ```
 
-## 预置不安装列表配置
+4. 修改完成后，将install_list.json文件推送到设备上，并重启设备生效。
+
+```
+    hdc shell mount -o rw,remount /
+    hdc file send install_list.json /system/etc/app/install_list.json
+    hdc shell reboot
+```
+
+## 更新预置应用
+
+预置应用更新后，使用如下方法重新安装。
+
+- 方法一：直接清空data，重启设备，应用会自动安装。
+
+```
+    hdc shell mount -o rw,remount / 
+    hdc shell rm /data/* -rf
+    hdc shell sync
+    hdc shell /system/bin/udevadm trigger
+    hdc shell reboot
+```
+- 方法二：执行如下命令，重启设备，应用即可安装。
+
+    如果应用之前已经安装过，这时推送新的hap到/system/app/路径下，需保证应用的版本号（Stage模型下对应app.json5配置文件中的[versionCode](../../application-dev/quick-start/app-configuration-file.md)标签；FA模型下对应配置文件中的[code](../../application-dev/quick-start/app-structure.md#version对象内部结构)标签）大于之前的版本号。 
+
+```
+    hdc shell mount -o rw,remount /
+    hdc shell param set persist.bms.test-upgrade true
+    hdc shell reboot
+```
+
+# 预置不安装列表配置
 
 [uninstall_list.json](https://gitee.com/openharmony/vendor_hihope/blob/master/rk3568/preinstall-config/uninstall_list.json)的配置优先级高于install_list.json,在该文件中配置后，则对应的预置应用不会安装。
