How does it actually work

Hi, this looks really cool, but I'm struggling to understand what exactly may does under the hood to make things work. I couldn't find any documentation about this, except for the fact that it apparently uses some generator framework of yours, which somehow supports coroutines.

How is the runtime engine different from Rust's async, how does it compare to Go's Goroutines and Java's Fibers?
