embassy-sync

An Embassy project.

Synchronization primitives and data structures with async support:

  • Channel - A Multiple Producer Multiple Consumer (MPMC) channel. Each message is only received by a single consumer.
  • PubSubChannel - A broadcast channel (publish-subscribe) channel. Each message is received by all consumers.
  • Signal - Signalling latest value to a single consumer.
  • Mutex - Mutex for synchronizing state between asynchronous tasks.
  • Pipe - Byte stream implementing embedded_io traits.
  • WakerRegistration - Utility to register and wake a Waker.
  • AtomicWaker - A variant of WakerRegistration accessible using a non-mut API.
  • MultiWakerRegistration - Utility registering and waking multiple Waker’s.
