* Return a concrete type from `server::listen`. * Change `FutureServiceExt::listen` to return `(SocketAddr, Listen)`, where `Listen` is a struct created by the `service!` macro that `impls Future<Item=(), Error=()>` and represents server execution. * Disable `conservative_impl_trait` as it's no longer used. * Update `FutureServiceExt` doc comment. * Update `SyncServiceExt` doc comment. Also annotate `server::Handle` with `#[must_use]`. * `cargo fmt`
