Enum Outcome 

pub enum Outcome {
    Continue,
    Respond(ReplyData),
}

What a middleware’s before hook decided.

Variants

Continue

Carry on — run the next middleware (and, eventually, the handler).

Respond(ReplyData)

Short-circuit: build this reply and return it. The handler and any remaining before hooks are skipped (after hooks still run on the reply). Use Outcome::Respond(reply::empty()), a reply::build_reply() for an explicit status/headers, etc. — anything a handler could return.
