Crate async_rwlock

An async reader-writer lock.

The locking strategy is fair: neither readers nor writers will be starved, assuming the task executor is also fair.

Examples

use async_rwlock::RwLock;

let lock = RwLock::new(5);

// Multiple read locks can be held at a time.
let r1 = lock.read().await;
let r2 = lock.read().await;
assert_eq!(*r1, 5);
assert_eq!(*r2, 5);
drop((r1, r2));

// Only one write lock can be held at a time.
let mut w = lock.write().await;
*w += 1;
assert_eq!(*w, 6);

Structs

RwLock	An async reader-writer lock.
RwLockReadGuard	A guard that releases the read lock when dropped.
RwLockWriteGuard	A guard that releases the write lock when dropped.
