Struct RawCondvar 

pub struct RawCondvar { /* private fields */ }

A raw condition variable.

Waits never return spuriously. notify_one returns exactly whether a waiting thread was selected for notification, and notify_all returns the exact number of waiting threads selected. A thread requeued directly onto the associated mutex is considered notified.

Trait Implementations

impl RawCondvar for RawCondvar

const INIT: Self

Initial value for a new condvar.

type RawMutex = RawMutex

The type of RawMutex this condvar can work with.

unsafe fn wait(&self, mutex: &RawMutex, _guard: &mut GuardNoSend)

Atomically unlocks the mutex and waits, then re-locks the mutex before returning.

fn notify_one(&self) -> bool

Notifies one waiting thread.

fn notify_all(&self) -> usize

Notifies all waiting threads.

impl RawCondvarTimed for RawCondvar

fn checked_duration_to_instant(timeout: &Duration) -> Option<Instant>

Converts a relative timeout into an absolute timeout.

unsafe fn wait_for( &self, mutex: &RawMutex, _guard: &mut GuardNoSend, timeout: &Duration, ) -> bool

Atomically unlocks the mutex and waits for a notification, a spurious wakeup, or the timeout to be reached, then re-locks the mutex before returning.

unsafe fn wait_until( &self, mutex: &RawMutex, _guard: &mut GuardNoSend, timeout: &Instant, ) -> bool

Atomically unlocks the mutex and waits for a notification, a spurious wakeup, or the timeout to be reached, then re-locks the mutex before returning.
