What are y'all's thoughts on Async in embedded? A portion of the Rust embedded OSS community really likes it as an abstraction over interrupts, critical sections etc. I've been burned by over-complexity and coloring problems with it before, eg in web programming.

Do you think it's a good fit? Use-case-dependent? Maybe for things like RF?

I'm very excited about this for one simple stupid reason: sleep(). Awaiting a timer delay deep inside some code is gonna be amazing. With typical sync code, you basically have to split your code and queue up the next work somewhere that would be picked up by the timer interrupt… basically doing the whole state-keeping that async would do for you.
