I believe these green threads work well when there’s good support in both language, runtime and standard library. I have built complicated concurrent software in C# with async-await. I don’t program golang but I heard the concurrency model works rather well in golang too, probably for the same reason as C#: good support in the language and the runtime.

I have no idea about Tokyo. I don’t program Rust, and the feedback I read about async/await was mixed.
