Description

https://docs.rs/axum/latest/axum/extract/derive.FromRequest.html#the-whole-type-at-once claims that:

The rejection will be the “via extractors”’s rejection. For the previous example that would be axum::extract::rejection::ExtensionRejection.

but from what I've found, this is incorrect. I've tried to use #[from_request(via(Query))] on a struct, assuming that the corresponding rejection would be QueryRejection, but instead axum::response::Response was put in the derived impl (documented as the default at https://docs.rs/axum/0.8.1/axum/extract/derive.FromRequest.html#the-rejection).

I assume that this is a bug in the derive macro for at least FromRequestParts, but probably FromRequest too.
