Module sync

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

Structs

• Barrier
  A barrier enables multiple threads to synchronize the beginning of some computation.
• BarrierWaitResult
  A BarrierWaitResult is returned by wait when all threads in the Barrier have rendezvoused.
• Mutex
  An asynchronous mutual exclusion primitive useful for protecting shared data
• MutexGuard
  A handle to a held Mutex.
• RwLock
  An asynchronous reader-writer lock
• 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 aquisition.
• SemaphorePermit
  A permit from the semaphore
