Wrong intra-doc links to methods on type aliases

[WojciechMula]

Hi, first of all sorry if it's not the correct repository for reporting this kind of error, but I noticed this on docs.rs.

Steps to reproduce:

1. Go to https://docs.rs/image/latest/image/type.RgbImage.html
2. Find method get_pixel -- this item links to the trait method with URL fragment https://docs.rs/image/latest/image/struct.ImageBuffer.html#tymethod.get_pixel
3. However, on the struct ImageMethod page, all methods have HTML anchors starting with method... not tymethod...
4. As a result, clicking on the method name, moves us only to the trait's documentation, but not this specific method.

thi,

this looks like a rustdoc bug? @GuillaumeGomez ?

[GuillaumeGomez]

Yep it is.

@WojciechMula: can you try with nightly?

[GuillaumeGomez]

Asking because we recently fixed bugs around anchors recently in #148543.

@GuillaumeGomez docs.rs is building with nightly? ;)

build also looks like it was after your fix?

[GuillaumeGomez]

Ah right. So still a bug (or maybe a new one). Checking that in the next days then.

Some more details about this bug: on type aliases, methods (not necessarily from traits) don't link to the correct upstream method. I wonder whether we should link to the upstream type like we currently do or to the current page method (like we do for deref). For now I'll keep the same behaviour and fix the link generation but might be worth discussing it later on.
