I don't like the "what color is your function" post, because it presents Go's M:N solution as something new, when in fact it's just a user-mode implementation of threads just like NGPT was back in the early aughts. In fact, we have M:N in Rust too. It's not sufficient for people's performance needs, which is why async I/O exists. Either 1:1 threads or mioco might be sufficient for your performance needs; if so, you're free to use them and you won't have to worry about red or blue functions!
