Tracking Issue for Thread::{into_raw, from_raw}

[ibraheemdev]

Feature gate: #![feature(thread_raw)]

This is a tracking issue for Thread::into_raw and Thread::from_raw.

These functions allow conversions between a Thread and a raw pointer, which is useful in concurrent code as it allows storing a Thread in an AtomicPtr.

Public API

// std::thread

impl Thread {
    fn into_raw(self) -> *const ();
    unsafe fn from_raw(ptr: *const ()) -> Thread;    
}
