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.
