KeyLock
Simple library for mutual exclusion based on keys. Lock and wait for execution by key.
Usage
Import the project using:
cargo add key-lock
Example
use key_lock::KeyLock;
#[tokio::main]
async fn main() {
// Initialize new lock.
let lock = KeyLock::new();
// Lock A, continues immediately.
let _a = lock.lock("a").await;
// Lock B, continues immediately.
let _b = lock.lock("b").await;
// Try to lock A, but it is already locked. Normal locking would block here.
assert!(lock.try_lock("a").await.is_err());
}
