Tracking Issue for raw array getters (array_ptr_get)

Feature gate: #![feature(array_ptr_get)]

This is a tracking issue for as_(mut_)ptr and as_(mut_)slice methods on raw array pointers, i.e. *(const/mut) [T; N].

See also:

• Similar methods for raw slices: https://github.com/rust-lang/rust/issues/74265

Public API

impl<T, const N: usize> *mut [T; N] {
    pub fn as_mut_ptr(self) -> *mut T {}
    pub fn as_mut_slice(self) -> *mut [T] {}
}

impl<T, const N: usize> *const [T; N] {
    pub const fn as_ptr(self) -> *const T {}
    pub const fn as_slice(self) -> *const [T] {}
}

Steps / History

• ACP: https://github.com/rust-lang/libs-team/issues/321
• Implementation: #119411
• Final comment period (FCP)^1
• Stabilization PR

Unresolved Questions

• If arbitrary_self_types (https://github.com/rust-lang/rfcs/pull/3519) is accepted, these methods may be changed to have a *(const/mut) Self receiver. Also, if a deref-like coercion mechanism is added (specifically, *[T; N] -> *[T], similar to the non-raw counterparts), these methods might become redundant.

Start by reviewing the feature-gated API and the completed implementation in #119411, then read the linked stabilization guidance and the unresolved questions. Done means completing the remaining final comment period and stabilization PR steps for array_ptr_get.
