Middleware definition

Provided Methods

fn start(&self, req: &HttpRequest<S>) -> Result<Started>

Method is called when request is ready. It may return future, which should resolve before next middleware get called.

fn response(&self, req: &HttpRequest<S>, resp: HttpResponse) -> Result<Response>

Method is called when handler returns response, but before sending http message to peer.

fn finish(&self, req: &HttpRequest<S>, resp: &HttpResponse) -> Finished

Method is called after body stream get sent to peer.
