    A few weeks ago we blogged about what's required on the compiler & language side to enable async/await in no_std In this new post we take look into how async could be used in embedded Rust programs and share why we are excited about async on embeddedhttps://ferrous-systems.com/blog/async-on-embedded/ …

        One of the challenges with these async constructs is that they are harder to reason about in terms of low level behavior. How do you grapple with this?

        How do you decide what APIs are async? Shouldn't GPIO be async? For example when I want to control a GPIO expander over a bus, then I'd have to wrap the async bus API into a blocking one? What if the peripheral I'm talking to requires a startup time? Am I blocking there?

        that makes gpio seriously heavyweight, but I get your point. assuming you only have one core than it's more of a low/deterministic latency question than a performance question. a RTFM kind of a kernel seriously mitigate the problem

        What is the consensus since AsyncRead/Write are not finalized? Do you import the traits from another crate?

        On embedded systems with libcore, Read/Write and AsyncRead/Write don't exist, so it kind of sidesteps the question.
