rvolosatovs opened PR #11684 from rvolosatovs:feat/async-util to bytecodealliance:main:

A few fairly small improvements:

Introduce a blanket implementation of FutureProducer for Future, which allows calling poll_produce on any Future

Move StreamEmptyProducer from wasmtime_wasi to wasmtime for better reusability and discoverability for embeders

@alexcrichton I've pushed https://github.com/bytecodealliance/wasmtime/pull/11684/commits/e3ad380aac2adb93c58490abbdd84b9b0cd34a60 with quite a bit more functionality, would you re-review?
I've also added a few StreamProducer implementations for common collections to hopefully make life easier for embedders. Happy to drop that completely and/or extract into a separate PR if there are concerns about doing that.

I was hoping to write some tests for these as well, but ran out of time. I can address that tomorrow
