# 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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
