Expand description

An async mutex.

Implementations

Creates a new async mutex.

Examples
use async_mutex::Mutex;

let mutex = Mutex::new(0);

Consumes the mutex, returning the underlying data.

Examples
use async_mutex::Mutex;

let mutex = Mutex::new(10);
assert_eq!(mutex.into_inner(), 10);

Acquires the mutex.

Returns a guard that releases the mutex when dropped.

Examples
use async_mutex::Mutex;

let mutex = Mutex::new(10);
let guard = mutex.lock().await;
assert_eq!(*guard, 10);

Attempts to acquire the mutex.

If the mutex could not be acquired at this time, then None is returned. Otherwise, a guard is returned that releases the mutex when dropped.

Examples
use async_mutex::Mutex;

let mutex = Mutex::new(10);
if let Some(guard) = mutex.try_lock() {
    assert_eq!(*guard, 10);
}

Returns a mutable reference to the underlying data.

Since this call borrows the mutex mutably, no actual locking takes place – the mutable borrow statically guarantees the mutex is not already acquired.

Examples
use async_mutex::Mutex;

let mut mutex = Mutex::new(0);
*mutex.get_mut() = 10;
assert_eq!(*mutex.lock().await, 10);

Acquires the mutex and clones a reference to it.

Returns an owned guard that releases the mutex when dropped.

Examples
use async_mutex::Mutex;
use std::sync::Arc;

let mutex = Arc::new(Mutex::new(10));
let guard = mutex.lock_arc().await;
assert_eq!(*guard, 10);

Attempts to acquire the mutex and clone a reference to it.

If the mutex could not be acquired at this time, then None is returned. Otherwise, an owned guard is returned that releases the mutex when dropped.

Examples
use async_mutex::Mutex;
use std::sync::Arc;

let mutex = Arc::new(Mutex::new(10));
if let Some(guard) = mutex.try_lock() {
    assert_eq!(*guard, 10);
}
