Struct serde::lib::core::thread::Thread

1.0.0 · source ·
pub struct Thread {
    inner: Pin<Arc<Inner>>,
}
Expand description

A handle to a thread.

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

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.

Fields

inner: Pin<Arc<Inner>>

Implementations

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();

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);

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();

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();
