# Since stm32 crates take SO LONG to build, we split them
# into a separate job. This way it doesn't slow down updating
# the rest.
strategy:
matrix:
crates:
- stm32
- rest
# This will ensure at most one doc build job is running at a time
# (for stm32 and non-stm32 independently).
# If another job is already running, the new job will wait.
# If another job is already waiting, it'll be canceled.
# This means some commits will be skipped, but that's fine because
# we only care that the latest gets built.

# embassy-sync
Synchronization primitives and data structures with an async API:
An [Embassy](https://embassy.dev) project.
Synchronization primitives and data structures with async support:
- [`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.
- [`Mutex`](mutex::Mutex) - 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.
## Interoperability
Futures from this crate can run on any executor.
## Minimum supported Rust version (MSRV)
Embassy is guaranteed to compile on the latest stable Rust version at the time of release. It might compile with older versions but that may change in any new patch release.
## License
