Module tokio::sync

This is supported on feature="sync" only.

Future-aware synchronization

This module is enabled with the sync feature flag.

Tasks sometimes need to communicate with each other. This module contains basic abstractions for doing so:

• oneshot, a way of sending a single value from one task to another.
• mpsc, a multi-producer, single-consumer channel for sending values between tasks.
• Mutex, an asynchronous Mutex-like type.
• watch, a single-producer, multi-consumer channel that only stores the most recently sent value.

Modules

broadcast	feature="sync" A multi-producer, multi-consumer broadcast queue. Each sent value is seen by all consumers.
mpsc	feature="sync" A multi-producer, single-consumer queue for sending values across asynchronous tasks.
oneshot	feature="sync" A channel for sending a single message between asynchronous tasks.
watch	feature="sync" A single-producer, multi-consumer channel that only retains the last sent value.

Structs

Barrier	feature="sync" A barrier enables multiple threads to synchronize the beginning of some computation.
BarrierWaitResult	feature="sync" A BarrierWaitResult is returned by wait when all threads in the Barrier have rendezvoused.
Mutex	feature="sync" An asynchronous mutual exclusion primitive useful for protecting shared data
MutexGuard	feature="sync" A handle to a held Mutex.
Semaphore	feature="sync" Counting semaphore performing asynchronous permit aquisition.
SemaphorePermit	feature="sync" A permit from the semaphore
