Struct std::thread::ThreadId

pub struct ThreadId(_);

A unique identifier for a running thread.

A ThreadId is an opaque object that has a unique value for each thread that creates one. ThreadIds are not guaranteed to correspond to a thread's system-designated identifier. A ThreadId can be retrieved from the id method on a Thread.

Examples

use std::thread;

let other_thread = thread::spawn(|| {
    thread::current().id()
});

let other_thread_id = other_thread.join().unwrap();
assert!(thread::current().id() != other_thread_id);

Implementations

impl ThreadId[src]

pub fn as_u64(&self) -> NonZeroU64[src]

🔬 This is a nightly-only experimental API. (thread_id_value #67939)

This returns a numeric identifier for the thread identified by this ThreadId.

As noted in the documentation for the type itself, it is essentially an opaque ID, but is guaranteed to be unique for each thread. The returned value is entirely opaque -- only equality testing is stable. Note that it is not guaranteed which values new threads will return, and this may change across Rust versions.
