Feature gate: #![feature(cast_maybe_uninit)]

This is a tracking issue for the cast_init and cast_uninit methods on pointers.

Public API

impl<T> *const T {
    pub const fn cast_uninit(self) -> *const MaybeUninit<T>;
}
impl<T> *mut T {
    pub const fn cast_uninit(self) -> *mut MaybeUninit<T>;
}
impl<T> NonNull<T> {
    pub const fn cast_uninit(self) -> NonNull<MaybeUninit<T>>;
}
impl<T> *const MaybeUninit<T> {
    pub const fn cast_init(self) -> *const T;
}
impl<T> *mut MaybeUninit<T> {
    pub const fn cast_init(self) -> *mut T;
}
impl<T> NonNull<MaybeUninit<T>> {
    pub const fn cast_init(self) -> NonNull<T>;
}
