Struct otter_api_tests::thread::ThreadId1.19.0[][src]

pub struct ThreadId(_);
Expand description

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

🔬 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.

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

Use this to upcast a trait to one of its supertraits. Read more

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more
