Expand description

Utilities for the array primitive type.

See also the array primitive type.

## Structs

- IntoIter
  A by-value array iterator.
- TryFromSliceError
  The error type returned when a conversion from a slice to an array fails.

## Functions

- try_from_fn Experimental
  Creates an array `[T; N]` where each fallible array element `T` is returned by the `cb` call. Unlike `from_fn`, where the element creation can’t fail, this version will return an error if any element creation was unsuccessful.
- from_fn
  Creates an array of type [T; N], where each element `T` is the returned value from `cb` using that element’s index.
- from_mut
  Converts a mutable reference to `T` into a mutable reference to an array of length 1 (without copying).
- from_ref
  Converts a reference to `T` into a reference to an array of length 1 (without copying).
