Your favorite llm will give you several good options. You can use an mpsc channel where you have a task per sender which waits on each branch in the select and then sends a message and then just wait on the receiver end of that channel. Or you could use https://docs.rs/futures/latest/futures/future/fn.select.html (or the select_all version). Both make it more obvious what is going on. The last way would be to implement a future manually. This would probably be my favorite option in many cases as it would be least overhead, but if you've never implemented a future it may be a bit intimidating.

Edit: tokio docs actually provide several suggestions: https://docs.rs/tokio/latest/tokio/macro.select.html#alterna...
