Feature gate: #![feature(ptr_cast_array)]

This is a tracking issue for the method for casting pointers to elements to pointers to arrays.

Public API

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