I have come across a weird behavior so I’m curious if it’s by design and if so why? ContextI’m writing a library to make it easy to write Cloud Foundry Route Services which are basically an app on cf acting as a guard and reverse proxy. Theres already a crate basically just proxying a Behavior seenTo call my proxying function pub async fn proxy_request( req: Request<Body> ) { I need to have the request so: pub async fn handle(req: Request<_>) {Until now, everything works ok. If I would like to have a header at my disposal async fn handle(req: Request<_>, TypedHeader(meta): TypedHeader<ProxyMetadata>) {The request failes with the message: Now If I remove the
Reason why this sucksNow I get it Is this by design? PS: Didn't open an issue as from me its a general question |

Thanks 😊 The docs are really nice and extensive but as a new one to axum I find it a bit hard to find the right pieces. Is there something in the docs.rs search where not only parameters, names and return types are searched but also all the documentation? |

I don't think so. Generally axum's docs is structured such that each top level module gives an overall idea of how to use that subset, since many of the types inside are used in similar ways. So I'd recommend reading the docs for each top level module to get a good understand of how things fit together. You're also welcome to make PRs with suggestions for improvements 😊 |

Don’t get me wrong, the docs are awesome but the docs.rs search for this kind of extensive documentation doesn’t really seem UX friendly as its more like a types search rather than a doc search |
