    How does async work in async-std?

(Phaiax - 2019/12/1 - CC_BY_SA 4.0)
Lately I was porting a software from tokio/futures-1.0 to async-await.
I somehow thought async-std was the successor of tokio and ported everything to async-std.
80% in, I noticed that my hyper dependency requires tokio and that it's not possible to replace tokio with async-std without also replacing hyper. Also, tokio and async-std try to solve the same problem. So I started a journey into the inners of the rust async story to find out if it is possible to use both tokio and async-std at the same time. (tl;dr: it is). I had heard of reactors and executors before, but there was much new stuff to discover.
