Crate embassy_futures

embassy-futures

An Embassy project.

Utilities for working with futures, compatible with no_std and not using alloc. Optimized for code size, ideal for embedded systems.

• Future combinators, like join and select
• Utilities to use async without a fully fledged executor: block_on and yield_now.

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.
