Module filter

Source
Expand description

Conditionally dispatch requests to the inner service based on the result of a predicate.

Unlike filter mod in tower, this let you return a custom response to user when the request is rejected.

§Example

     Router::new()
         .route("/get", get(|| async { "get works" }))
         .layer(FilterExLayer::new(|request: Request<Body>| {
             if let Some(_auth) = request.headers().typed_get::<Authorization<Basic>>() {
                 // TODO: do something
                 Ok(request)
            } else {
                Err(StatusCode::UNAUTHORIZED.into_response())
            }
         }));
