How to extract the referer's header value?

[BenJeau]

Summary

Hi, I'm using axum_extra's TypedHeader to extract the referer, but I'm a bit confused to as how I'm supposed to get it's value. I can log it with it's debug implementation, but not get it's value.

It seems like I need to use HeaderMap as an extractor instead of TypedHeader<Referer>? I guess I'm just a bit confused as to why I can extract the value for some headers with TypedHeader, but not all (or was wondering if it was just a fault from my side).

Thanks :)

axum version

0.7.2

After some digging I'm seeing some PRs in the headers crate, which I guess can explain this hyperium/headers#95 since I think axum just piggy backs off of that crate?

Exactly. Nothing axum can do about this unfortunately.

Wanted to make sure I read the source code correctly, thanks for the reply :)
