Interest in more builtin HTTP extractors

[jordanisaacs]

I am working on building a tracing library for Axum and one thing that I noticed coming from Actix Web is that many ease of use extractors are missing for requests. For example Actix has an implementation to match the pattern of the request, and a ConnectionInfo which parses the headers for you. I feel this would be best suited to be part of Axum but I am curious about other people's thoughts.

For reference here is Actix's HttpRequest documentation: https://docs.rs/actix-web/3.3.2/actix_web/struct.HttpRequest.html#method.connection_info

What specific things are you looking for?

Seems to be axum has the things in actix_web::dev::ConnectionInfo already:

• Router::into_make_service_with_connect_info gives you remote address
• Uri gives you the URI including the scheme
• HeaderMap and TypedHeader gives you headers
