Hi!

It seems to me that many internal functions such as call_async or wrap_async have explicit requirements on Send + Sync. Is there any way of running wasmtime with a non-multithreaded runtime, or is it mainly supposed to integrate well with tokio?

Cheers

Currently, no, there's no support for futures without Send/Sync natively in the API. It may be possible with unsafe wrappers that document that it's not actually used in a Send/Sync context but short of that Wasmtime isn't well-built for this use case unfortunately.

Thanks for the great answer.
