It would be more interesting if it was on how to combine C++20 co-routines with Rust async-await models.
Combining single-threaded C++ with multi-threaded languages has been a thing for quite some time.
Wow, I wouldn't have thought that it would be possible to do this (at least, not ergonomically, although now that you mention it I guess I don't see why not). That would be amazing to see.
I have done this integrating wasmtime into a a C++ seastar.io application. I’ll have to write a post about it
