Module sync 

Modules

broadcast

A multi-producer, multi-consumer broadcast queue. Each sent value is seen by all consumers.

futures

Named future types.

mpsc

A multi-producer, single-consumer queue for sending values between asynchronous tasks.

oneshot

A one-shot channel is used for sending a single message between asynchronous tasks. The channel function is used to create a Sender and Receiver handle pair that form the channel.

watch

A multi-producer, multi-consumer channel that only retains the last sent value.

Structs

AcquireError

Error returned from the Semaphore::acquire function.

Barrier

A barrier enables multiple tasks to synchronize the beginning of some computation.

BarrierWaitResult

A BarrierWaitResult is returned by wait when all tasks in the Barrier have rendezvoused.

MappedMutexGuard

A handle to a held Mutex that has had a function applied to it via MutexGuard::map.

Mutex

An asynchronous Mutex-like type.

MutexGuard

A handle to a held Mutex. The guard can be held across any .await point as it is Send.

Notify

Notifies a single task to wake up.

OnceCell

A thread-safe cell that can be written to only once.

OwnedMappedMutexGuard

A owned handle to a held Mutex that has had a function applied to it via OwnedMutexGuard::map.

OwnedMutexGuard

An owned handle to a held Mutex.

OwnedRwLockMappedWriteGuard

Owned RAII structure used to release the exclusive write access of a lock when dropped.

OwnedRwLockReadGuard

Owned RAII structure used to release the shared read access of a lock when dropped.

OwnedRwLockWriteGuard

Owned RAII structure used to release the exclusive write access of a lock when dropped.

OwnedSemaphorePermit

An owned permit from the semaphore.

RwLock

An asynchronous reader-writer lock.

RwLockMappedWriteGuard

RAII structure used to release the exclusive write access of a lock when dropped.

RwLockReadGuard

RAII structure used to release the shared read access of a lock when dropped.

RwLockWriteGuard

RAII structure used to release the exclusive write access of a lock when dropped.

Semaphore

Counting semaphore performing asynchronous permit acquisition.

SemaphorePermit

A permit from the semaphore.

SetOnce

A thread-safe cell that can be written to only once.

SetOnceError

Error that can be returned from SetOnce::set.

TryLockError

Error returned from the Mutex::try_lock, RwLock::try_read and RwLock::try_write functions.

Enums

SetError

Errors that can be returned from OnceCell::set.

TryAcquireError

Error returned from the Semaphore::try_acquire function.
