Crate parking

Thread parking and unparking.

A parker is in either notified or unnotified state. Method park() blocks the current thread until the parker becomes notified and then puts it back into unnotified state. Method unpark() puts it into notified state.

Examples

use std::thread;
use std::time::Duration;
use parking::Parker;

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

// Notify the parker.
u.unpark();

// Wakes up immediately because the parker is notified.
p.park();

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

// Wakes up when `u.unpark()` notifies and then goes back into unnotified state.
p.park();
