* Move connections-clone down a bit * Use `Ok` and `Err` as IntoFuture
* Send source address of message in addition to the message to connected clients. * Move `spawn_fn` to the bottom. * Use `map` instead of `and_then` if there is no need for blocking. * `map` to unit where values are not needed anymore.
* Remove unnecessary clone * Improve rightward drift * Remove unnecessary lazy future * Improve utf-8 handling * Refactor to make code more understandable
