Feature gate: #![feature(slice_as_array)]

This is a tracking issue for adding conversion functions from slices to arrays.

impl [T] { pub const fn as_array(&self) -> Option<&[T; N]>;

pub const fn as_mut_array<const N: usize>(&mut self) -> Option<&mut [T; N]>;

}

impl *const [T] { pub const fn as_array(self) -> Option<*const [T; N]>; }

impl *mut [T] { pub const fn as_mut_array(self) -> Option<*mut [T; N]>; }

// alloc::boxed

impl Box<[T]> { pub fn into_array(self) -> Option<Box<[T; N]>>; }

// alloc::rc

impl Rc<[T]> { pub fn into_array(self) -> Option<Rc<[T; N]>>; }

// alloc::sync

impl Arc<[T]> { pub fn into_array(self) -> Option<Arc<[T; N]>>; }

API change proposal (ACP): #496
Implementation for [T], *const [T], and *mut [T]: Add as_array and as_mut_array conversion methods to slices. #133512
Fix docs for <[T]>::as_array: Fix docs for <[T]>::as_array. #133743
Implementation for Box<[T]>, Rc<[T]>, and Arc<[T]>: Add into_array conversion destructors for Box, Rc, and Arc. #134379
