Struct crossbeam_utils::sync::Unparker

pub struct Unparker { /* fields omitted */ }

Unparks a thread parked by the associated Parker.

Methods

impl Unparker

pub fn unpark(&self)

Atomically makes the token available if it is not already.

This method will wake up the thread blocked on park or park_timeout, if there is any.

Examples

use std::thread;
use std::time::Duration;
use crossbeam_utils::sync::Parker;

let mut p = Parker::new();
let u = p.unparker().clone();

thread::spawn(move || {
    thread::sleep(Duration::from_millis(500));
    u.unpark();
});

// Wakes up when `u.unpark()` provides the token, but may also wake up
// spuriously before that without consuming the token.
p.park();
