Struct sync_wait_object::windows::AutoResetEvent

pub struct AutoResetEvent(_);

Wrapper of WaitEvent of type bool, which focuses on waiting for true with automatic reset to false.

Examples

use std::{ thread, sync::Arc, sync::atomic::{ AtomicU8, Ordering } };
use sync_wait_object::SignalWaitable;

let ev = AutoResetEvent::new();
let mut signal = ev.clone();

let mut next = AutoResetEvent::new();
let wait_next = next.clone();

let v = Arc::new(AtomicU8::new(0));
let v_setter = v.clone();

thread::spawn(move || {
    v_setter.store(1, Ordering::SeqCst);
    signal.set().unwrap();

    wait_next.wait_until_set().unwrap();

    v_setter.store(2, Ordering::SeqCst);
    signal.set().unwrap();
});

ev.wait_until_set().unwrap();
assert_eq!(v.load(Ordering::SeqCst), 1);

next.set().unwrap();

ev.wait_until_set().unwrap();
assert_eq!(v.load(Ordering::SeqCst), 2);
