# 1.0.0[−][src]Struct std::thread::Thread

    pub struct Thread { /* fields omitted */ }

A handle to a thread.

Threads are represented via the `Thread` type, which you can get in one of two ways:

- By spawning a new thread, e.g., using the `thread::spawn` function, and calling `thread` on the `JoinHandle`.
- By requesting the current thread, using the `thread::current` function.

The `thread::current` function is available even for threads not spawned by the APIs of this module.

There is usually no need to create a `Thread` struct yourself, one should instead use a function like `spawn` to create new threads, see the docs of `Builder` and `spawn` for more details.

## Methods

### `impl Thread`[src]

#### `pub fn unpark(&self)`[src]

Atomically makes the handle's token available if it is not already.

Every thread is equipped with some basic low-level blocking support, via the `park` function and the `unpark()` method. These can be used as a more CPU-efficient implementation of a spinlock.

See the park documentation for more details.

# Examples

    use std::thread;
    use std::time::Duration;

    let parked_thread = thread::Builder::new()
        .spawn(|| {
            println!("Parking thread");
            thread::park();
            println!("Thread unparked");
        })
        .unwrap();

    // Let some time pass for the thread to be spawned.
    thread::sleep(Duration::from_millis(10));

    println!("Unpark the thread");
    parked_thread.thread().unpark();

    parked_thread.join().unwrap();Run

#### `pub fn id(&self) -> ThreadId`1.19.0[src]

Gets the thread's unique identifier.

# 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

#### `pub fn name(&self) -> Option<&str>`[src]

Gets the thread's name.

For more information about named threads, see this module-level documentation.

# Examples

Threads by default have no name specified:

    use std::thread;

    let builder = thread::Builder::new();

    let handler = builder.spawn(|| {
        assert!(thread::current().name().is_none());
    }).unwrap();

    handler.join().unwrap();Run

Thread with a specified name:

    use std::thread;

    let builder = thread::Builder::new()
        .name("foo".into());

    let handler = builder.spawn(|| {
        assert_eq!(thread::current().name(), Some("foo"))
    }).unwrap();

    handler.join().unwrap();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`)
