# key-rwlock
Simple library for keyed asynchronous reader-writer locks.

## Example
```rust
use key_rwlock::KeyRwLock;

#[tokio::main]
async fn main() {
    let lock = KeyRwLock::new();

    let _foo = lock.write("foo").await;
    let _bar = lock.read("bar").await;

    assert!(lock.try_read("foo").await.is_err());
    assert!(lock.try_write("foo").await.is_err());

    assert!(lock.try_read("bar").await.is_ok());
    assert!(lock.try_write("bar").await.is_err());
}
```
