Struct timecat::thread::ThreadId

pub struct ThreadId(/* private fields */);

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

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

pub fn as_u64(&self) -> NonZero<u64>

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

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.

Trait Implementations

impl Clone for ThreadId

fn clone(&self) -> ThreadId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ThreadId

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for ThreadId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ThreadId

fn eq(&self, other: &ThreadId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
