Trait MessageHandler 

pub trait MessageHandler {
    type Interface: Interface;

    // Required method
    fn handle_message(
        &self,
        message: Self::Interface,
    ) -> impl Future<Output = ()> + Send;

    // Provided method
    fn name() -> &'static str { ... }
}

Basic building block for composing services.
