Async / Await / Generators / Coroutines in Plugins

[vincent-lecrubier-skydio]

Just discovered Extism today and it looks awesome!

One particular thing is missing for my use case: Support for Async / await / generators / coroutines in plugins. I don't see anything about this in the FAQ either. Have there been any thoughts about it?

Hi! Thanks for the kind words 😃

Which PDK language are you looking at with those limitations? JS?

[vincent-lecrubier-skydio]

My main candidates for plugin languages are Python (doesn't exist yet, I know :-) ) with asyncio, JS with standard promises and generators, and Rust with tokio.

I would like to add my usecase to this as well.

For me, my plugins need not be async. But they call a bunch of host functions which will be async. So technically the plugin would see all host functions as sync calls but the asynchronoucity would be provided by the host function and the host's runtime (tokio in my case)
