KeyLock

crates.io page docs.rs page license: MIT

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());
}
