async-on-embedded

async fn / .await on embedded (Cortex-M edition): no-global-alloc, no-threads runtime

Status: Proof of Concept. Do not use in production.

NOTE: Embassy is a maintained, production executor and library with similar functionality.

NOTE: This library contains known bugs.

Check nrf52/examples for an overview of what can be done with the runtime.

NOTE You need a rustc build that includes PR rust-lang/rust#69033
