No, it hasn't.

Actually C++20 comes with only the minimal support for coroutines in the std library. If you want to do anything useful, you need to implement a promise type yourself which is very hard to do without using one library that does that.

From the looks of it, and what I am already able to do with Visual C++ I bet it still is more functional than what Rust currently offers.

And that I won't need to rewrite it when I try out the same code with another C++20 compiler.
