[−][src]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 two 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

mpsc	`feature="sync"` and `feature="sync"` A multi-producer, single-consumer queue for sending values across asynchronous tasks.
oneshot	`feature="sync"` and `feature="sync"` A channel for sending a single message between asynchronous tasks.
watch	`feature="sync"` and `feature="sync"` A single-producer, multi-consumer channel that only retains the last sent value.

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`.
