Vec::iter not found in search in rustdoc

[pickfire]

In rust doc search, I can't find Vec::iter although iter is available in Vec.

https://doc.rust-lang.org/std/index.html?search=vec%3A%3Aiter

@pickfire it's there, it's just called slice::iter because it comes from the Deref impl.

Are you suggested rustdoc should show Deref methods in search? That seems useful, but a little complicated ... Search is already pretty buggy.

[pickfire]

Yeah, that would be good but do seemed a little bit complicated, the search for deref could have a lower score or shown with some sort of visual to know it's a Deref.

At least I didn't noticed that it's slice because the doc page is quite long and I don't know which function does it impl for. Quite a few times I wonder which impl I am looking at, scroll up tons of page and saw the wrong one.

Adding an alias works, if it's acceptable to solve this as a one-off.

Seems silly to do this for every single slice method. I think we should do this consistently if we do it at all.

[pickfire]

Yes, if we do it it should be added for everything that implements Deref for all types.
