rustdoc: From trait implementation in actix-web 4.0.0-beta.8 is missing from docs

[jplatte]

This page is missing any mention of this trait implementation despite there being no #[doc(hidden)] attribute on the impl or any of the involved types. I have no idea what might be going on.

The trait implementation you are referring to is not missing, in fact it's the latest on "Trait Implementations".

Now I'm really confused. I went over the page multiple times and found no generic From impl except the blanket impl from std. I searched for ResponseError on the page and it wasn't there in the later parts of the page. I guess I'll close this.

Turned out I linked the wrong error page, the type where I was expecting the impl to show up was actix_web::error::Error¹, a.k.a. actix_http::error::Error, which is not the same thing as actix_web::Error. There the impl really doesn't exist, at least in the same file (which has me very confused how the generics work out in practice but I'm okay with that for now).

¹ which also appears twice in the docs! (here)

It turned out that actix_web::error::Error is the same as actix_web::Error! The problem is rustdoc links to the wrong page (see my comment on #70380). This got me confused for hours!
