async/await in embedded is actually an interesting thing, that i also evaluated. I think it can't be an alternative to preemptive RTOS kernels, since the cooperative nature doesn't allow to process things within guaranteed deadlines. Therefore I think async/await might end up more as an add-on to RTOS: All time-critical things are run within independent RTOS tasks. And all the remaining and less critical stuff could potentially be run inside a single-threaded async/await scheduler. While Rust seems to be promising here, I'm not sure whether the current async/await implementation will really allow for this. I experimented a bit with it, and found lots of issues where async/await lead to severe memory bloat (composing 3 async functions that do not a lot things requiring a 20kB task allocation). The compatibility with Futures and the requirement to move async fns to compose them before using them (which requires extra stack - which again ends up as extra heap/task memory) plays a bit against it. But these things are also worked on, so let's seee how it works out.
