Tracking Issue for raw array getters (array_ptr_get)

[yotamofek]

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: Tracking Issue for raw slice getters (slice_ptr_get) #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: as_(mut_)ptr and as_(mut_)slice methods on raw array pointers libs-team#321
• Implementation: Add as_(mut_)ptr and as_(mut_)slice to raw array pointers #119411
• Final comment period (FCP)¹
• Stabilization PR

Unresolved Questions

• If arbitrary_self_types (Arbitrary self types v2 rfcs#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.

Hey so has it been long enough without problems to move for an FCP on this? It seems pretty cut and dry at this point, they do one obvious thing.
