//! # The Rust Standard Library
//!
//! The Rust Standard Library provides the essential runtime
//! functionality for building portable Rust software.
//! It is linked to all Rust crates by default.
//!
//! ## Intrinsic types and operations
//!
//! The [`ptr`](ptr/index.html), [`mem`](mem/index.html),
//! and [`cast`](cast/index.html) modules deal with unsafe pointers,
//! memory manipulation, and coercion.
//! [`kinds`](kinds/index.html) defines the special built-in traits,
//! and [`raw`](raw/index.html) the runtime representation of Rust types.
//! These are some of the lowest-level building blocks of Rust
//! abstractions.
//!
//! ## Math on primitive types and math traits
//!
//! Although basic operations on primitive types are implemented
//! directly by the compiler, the standard library additionally
//! defines many common operations through traits defined in
//! mod [`num`](num/index.html).
//!
//! ## Pervasive types
//!
//! The [`option`](option/index.html) and [`result`](result/index.html)
//! modules define optional and error-handling types, `Option` and `Result`.
//! [`iter`](iter/index.html) defines Rust's iterator protocol
//! along with a wide variety of iterators.
//! [`Cell` and `RefCell`](cell/index.html) are for creating types that
//! manage their own mutability.
//!
//! ## Vectors, slices and strings
//!
//! The common container type, `Vec`, a growable vector backed by an
//! array, lives in the [`vec`](vec/index.html) module. References to
//! arrays, `&[T]`, more commonly called "slices", are built-in types
//! for which the [`slice`](slice/index.html) module defines many
//! methods.
//!
//! UTF-8 strings, `~str` and `&str`, are built-in types, and the
//! standard library defines methods for them on a variety of traits
//! in the [`str`](str/index.html) module. Rust strings are immutable;
//! use the `StrBuf` type defined in [`strbuf`](strbuf/index.html)
//! for a mutable string builder.
//!
//! For converting to strings use the [`format!`](fmt/index.html)
//! macro, and for converting from strings use the
//! [`FromStr`](from_str/index.html) trait.
//!
//! ## Platform abstractions
//!
//! Besides basic data types, the standard library is largely concerned
//! with abstracting over differences in common platforms, most notably
//! Windows and Unix derivatives. The [`os`](os/index.html) module
//! provides a number of basic functions for interacting with the
//! operating environment, including program arguments, environment
//! variables, and directory navigation. The [`path`](path/index.html)
//! module encapsulates the platform-specific rules for dealing
//! with file paths.
//!
//! `std` also includes modules for interoperating with the
//! C language: [`c_str`](c_str/index.html) and
//! [`c_vec`](c_vec/index.html).
//!
//! ## Concurrency, I/O, and the runtime
//!
//! The [`task`](task/index.html) module contains Rust's threading abstractions,
//! while [`comm`](comm/index.html) contains the channel types for message
//! passing. [`sync`](sync/index.html) contains further, primitive, shared
//! memory types, including [`atomics`](sync/atomics/index.html).
//!
//! Common types of I/O, including files, TCP, UPD, pipes, Unix domain sockets,
//! timers, and process spawning, are defined in the [`io`](io/index.html).
//!
//! Rust's I/O and concurrency depends on a small runtime interface
//! that lives, along with its support code, in mod [`rt`](rt/index.html).
//! While a notable part of the standard library's architecture, this
//! module is not intended for public use.
//!
//! ## The Rust prelude and macros
//!
//! Finally, the [`prelude`](prelude/index.html) defines a set of
//! common set of traits, types, and functions that are made available
//! to all code by default. [`macros`](macros/index.html) contains
//! all the standard macros, such as `assert!`, `fail!`, `println!`.
