async-rwlock

An async reader-writer lock.

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

Examples

```rust 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; asserteq!(*r1, 5); asserteq!(*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); ```
