pub struct ThreadId(/* private fields */);Expand description
A unique identifier for a running thread.
A ThreadId is an opaque object that uniquely identifies each thread
created during the lifetime of a process. ThreadIds are guaranteed not to
be reused, even when a thread terminates. ThreadIds are under the control
of Rust’s standard library and there may not be any relationship between
ThreadId and the underlying platform’s notion of a thread identifier –
the two concepts cannot, therefore, be used interchangeably. A ThreadId
can be retrieved from the id method on a Thread.
§Examples
Implementations§
Source§impl ThreadId
impl ThreadId
Sourcepub fn as_u64(&self) -> NonZero<u64>
🔬This is a nightly-only experimental API. (thread_id_value #67939)
pub fn as_u64(&self) -> NonZero<u64>
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.
