Description

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;
}

Steps / History

• ACP: ACP: add Thread::into_raw and Thread::from_raw libs-team#200
• Implementation: Add Thread::{into_raw, from_raw} #97524
• Final comment period (FCP)
• Stabilization PR

Unresolved Questions

• Do we want to commit to guaranteeing that Thread can always be represented as a pointer/integer?
