Struct RawMutex

pub struct RawMutex { /* private fields */ }

Raw mutex type backed by the parking lot.

Trait Implementations

impl RawMutex for RawMutex

const INIT: RawMutex = _

Initial value for an unlocked mutex.

type GuardMarker = GuardNoSend

Marker type which determines whether a lock guard should be Send. Use one of the GuardSend or GuardNoSend helper types here.

fn lock(&self)

Acquires this mutex, blocking the current thread until it is able to do so.

fn try_lock(&self) -> bool

Attempts to acquire this mutex without blocking. Returns true if the lock was successfully acquired and false otherwise.

unsafe fn unlock(&self)

Unlocks this mutex.

fn is_locked(&self) -> bool

Checks whether the mutex is currently locked.

impl RawMutexFair for RawMutex

unsafe fn unlock_fair(&self)

Unlocks this mutex using a fair unlock protocol.

unsafe fn bump(&self)

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) -> bool

Attempts to acquire this lock until a timeout is reached.

fn try_lock_for(&self, timeout: Duration) -> bool

Attempts to acquire this lock until a timeout is reached.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
