Struct std::thread::ThreadId 1.19.0[−][src]
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. ThreadId
s 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);Run
Implementations
impl ThreadId
[src]
impl ThreadId
[src]pub fn as_u64(&self) -> NonZeroU64
[src]
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.
