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

An RAII implementation of a “scoped lock” of a Mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.

The data protected by the mutex can be accessed through this guard via its Deref and DerefMut implementations.

This guard can be held across any .await point, as it implements Send.

This structure is created by the lock and try_lock methods on Mutex.
