pub struct MutexGuard<'a, T: ?Sized> { /* private fields */ }
Expand description

An RAII guard returned by the lock and try_lock methods. When this structure is dropped (falls out of scope), the lock will be unlocked.

Implementations

Returns a locked view over a portion of the locked data.

Example
use futures::lock::{Mutex, MutexGuard};

let data = Mutex::new(Some("value".to_string()));
{
    let locked_str = MutexGuard::map(data.lock().await, |opt| opt.as_mut().unwrap());
    assert_eq!(&*locked_str, "value");
}
