  • PubSubChannel - A broadcast channel (publish-subscribe) channel. Each message is received by all consumers.
  • Signal - Signalling latest value to a single consumer.
  • Watch - Signalling latest value to multiple consumers.
  • 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.
  • LazyLock - A value which is initialized on the first access
