tendrils vs qutex vs async-priority-lock

Tiny, flexible helpers for managing shared state (Arc<Mutex<T>> / Arc<RwLock<T>>) safely in async Rust.

Synchronization mechanisms that rely on lock-free and other non-(thread)blocking techniques, such as Rust futures, to guarantee mutually exclusive or shared exclusive access to data.

A priority-based async lock. Optionally no-std.
