unsafe fn unlock(&self, _guard: Self::Guard)

Unlocks this mutex using a fair unlock protocol.

unsafe fn bump(&self, _guard: &mut Self::Guard)

Temporarily yields the mutex to a waiting thread if there is one.

impl RawMutexTimed for RawMutex

type Duration = Duration

Duration type used for try_lock_for.

type Instant = Instant

Instant type used for try_lock_until.

fn try_lock_until(&self, timeout: Instant) -> Option<Self::Guard>

Attempts to acquire this lock until a timeout is reached.

fn try_lock_for(&self, timeout: Duration) -> Option<Self::Guard>
