Crate embassy_sync
source ·Expand description
§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.PriorityChannel
- A Multiple Producer Multiple Consumer (MPMC) channel. Each message is only received by a single consumer. Higher priority items are sifted to the front of the channel.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 implementingembedded_io
traits.WakerRegistration
- Utility to register and wake aWaker
.AtomicWaker
- A variant ofWakerRegistration
accessible using a non-mut API.MultiWakerRegistration
- Utility registering and waking multipleWaker
’s.
§Interoperability
Futures from this crate can run on any executor.
