# embassy-sync Synchronization primitives and data structures with an async API: - [`Channel`](channel::Channel) - A Multiple Producer Multiple Consumer (MPMC) channel. Each message is only received by a single consumer. - [`PubSubChannel`](pubsub::PubSubChannel) - A broadcast channel (publish-subscribe) channel. Each message is received by all consumers. - [`Signal`](signal::Signal) - Signalling latest value to a single consumer. - [`Mutex`](mutex::Mutex) - A Mutex for synchronizing state between asynchronous tasks. - [`Pipe`](pipe::Pipe) - Byte stream implementing `embedded_io` traits. - [`WakerRegistration`](waitqueue::WakerRegistration) - Utility to register and wake a `Waker`. - [`AtomicWaker`](waitqueue::AtomicWaker) - A variant of `WakerRegistration` accessible using a non-mut API. - [`MultiWakerRegistration`](waitqueue::MultiWakerRegistration) - Utility registering and waking multiple `Waker`'s.
