Example

// Empty 200 OK
let ping = ServerMechanism::get("/ping")
    .onconnect(|| async { reply!() });

// Plain reply with a custom status
let gone = ServerMechanism::delete("/v1")
    .onconnect(|| async {
        reply!(message => warp::reply::html("endpoint deprecated"), status => Status::Gone)
    });

// JSON body, 200 OK
let list = ServerMechanism::get("/items")
    .onconnect(|| async {
        let items: Vec<Item> = vec![];
        reply!(json => items)
    });

// JSON body with a custom status
let create = ServerMechanism::post("/items")
    .json::<Item>()
    .onconnect(|item| async move {
