struct SendUserEmail { id: i32, msg: String };
struct NewUserLogin { id: i32 };

async fn foo() {
    // Create a mediator
    let mediator = MediatorBuilder::new()
        .add_handler(|x: NewUserRequest| {
            // get total users
            NewUserResponse { total_users: 13 }
        })
        .add_async_handler(|x: SendUserEmail| async move {
            // send email
            true
        })
        .listen_for::<NewUserLogin>()
        .add_notification_receiver(|x: &NewUserLogin| {
            println!("User {} logged in!", x.id);
        })
        .build();
        
    mediator.notify(&NewUserLogin { id: 5 });
    let response = mediator.handle(NewUserRequest { id: 5 });
    println!("There are now {} users in the system", response.total_users);
}

let mediator = MediatorBuilder::new()
    .build();
