How exactly do I write embedded code for a tiny chip on a different architecture with just 4K of RAM and no OS that uses the Win32 fibers?

Probably not using green threads / async at all? That would require a number of stacks as well as a little runtime, which will quickly eat up your 4K.

Just to clarify for those following along, Rust async code does not use green threads and doesn't require a stack per task.

I'm missing some of the technical details here, but from a quick glance of the article it seems like Rust's futures are lazy. I.e. a stack would only be allocated when the future is actually awaited. But in order to execute the relevant code, a call stack per not-finished future is still needed, or am I missing something?
