When using the `#[simd]` attribute on a tuple struct, the components of the
tuple struct must all be of a concrete, nongeneric type so the compiler can
reason about how to use SIMD with them. This error will occur if the types
are generic.
```
#[simd]
struct Bad<T>(T, T, T); // This will cause an error
#[simd]
struct Good(u32, u32, u32); // This will not
```
"##
,
E0075
:
r##"
The `#[simd]` attribute can only be applied to non empty tuple structs, because
it doesn't make sense to try to use SIMD operations when there are no values to
operate on.
```
#[simd]
struct Bad; // This will cause an error
#[simd]
struct Good(u32); // This will not
```

When using the `#[simd]` attribute to automatically use SIMD operations in tuple
struct, the types in the struct must all be of the same type, or the compiler
will trigger this error.
```
#[simd]
struct Bad(u16, u32, u32); // This will cause an error
#[simd]
struct Good(u32, u32, u32); // This will not
```

When using the `#[simd]` attribute on a tuple struct, the elements in the tuple
must be machine types so SIMD operations can be applied to them.
```
#[simd]
struct Bad(String); // This will cause an error
#[simd]
struct Good(u32, u32, u32); // This will not
