Tracking Issue for `box_uninit_write`

[workingjubilee]

Feature gate: #![feature(box_uninit_write)]

Split-out from #63291 as a result of stabilizing most of its API! It's a way to write to the MaybeUninit on the Box and thus initialize it!

Public API

impl<T, A> Box<MaybeUninit<T>, A> {
    pub fn write(mut boxed: Self, value: T) -> Box<T, A>;
}

Steps / History

• Implementation: #...
  • honestly have no idea
  • related API was added in Tracking issue for uninitialized constructors for Box, Rc, Arc #63291
• Final comment period (FCP)¹
• Stabilization PR

Unresolved Questions

• idk lol
