no_std support? about smol HOT 4 CLOSED

Closing this issue due to inactivity. I don't think it makes too much sense for smol to provide anything no_std. That would basically entail some parts of futures-lite, which you can use directly and disable the std feature flag in it.

I believe no_std support for async/await is coming with the next Rust version.

Well, which parts of smol would even be available in no_std environments? :) The reactor requires networking, which is provided by std. Blocking executor doesn't make sense without types for stdin/stdout/stderr and files. I could be missing something here, though!

I'm guessing this goes hand in hand with providing an interface for people to implement their own reactors. Embedded typically has to come up with their own TCP/IP stack like LWIP or PicoTCP.

See for example, this project that implements support for them: https://github.com/cesanta/mongoose
