I wonder whether there is any ongoing effort to unify the ecosystem between different runtimes. Specially considering that Tokio and futures (by extension async-std) implement their own Async* traits, it seems that it becomes even harder to write runtime agnostic libraries. It would be nice if these fundamental traits were part of rust std library.
