arbitrary-lock

Acquire a lock on an arbitrary key, like a string or integer.

Usage

Add the dependency to your project:

bash cargo add arbitrary-lock

Use the struct:

rust // This can be cheaply cloned. // The key must be Hash + Eq + Clone. // Provide your preferred lock type as the second generic argument. It must implement Default. let locker = ArbitraryLock::<String, tokio::sync::Mutex<()>>::new(); { let _l = locker.get("user:2185724".to_string()).lock().await; do_something_in_database().await; };
