I am yet to use async in c++, but I did work on a multi threaded c++ project for a few years

Rust is nicer for async and MT than c++ in every way. I am pretty sure.

But it's still mid. If you use Rust async aggressively you will struggle with the borrow checker and the architecture results of channel hell.

If you follow the "one control thread that does everything and never blocks" you can get far, but the language does not give you much help in doing that style neatly.

I have never used Go. I love a lot of Go projects like Forgejo and SyncThing. Maybe Go solved async. Rust did not. C++ did not even add good tagged unions yet.
