fast-async-mutex

The fast async mutex which uses atomics with spinlock algorithm. Spinlock algorithm integrated with the Rust futures concept without the overhead of any libs. Also when the MutexGuard is dropped, a waker of the next locker will be executed. It will be works with any async runtime in Rust, it may be a tokio, smol, async-std and etc..

Examples

```rust use fastasyncmutex::mutex::Mutex;

[tokio::main]

async fn main() { let mutex = Mutex::new(10); let guard = mutex.lock().await; assert_eq!(*guard, 10); } ```
