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. 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);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.
