Rustdoc rendering of underscore_imports a.k.a. impl-only-use is unuseful

[Nemo157]

I tried using a lot of pub use Foo as _; in futures to avoid issues with preludes and extension trait shadowing, unfortunately Rustdoc currently doesn't seem to have any special handling of this feature resulting in a big list of exported _ traits:

Well, looks as expected from my opinion. 🤣

What do you suggest that rustdoc should do in this case?

[Nemo157]

I really can't think of something that's super obvious. What I would want is to have the original name in there as the main link, but somehow making it obvious that the name isn't actually visible at this path.

Actually, looking at this a little more there is an actual bug here that really makes these docs unusable, all those _ traits link to the page futures/prelude/trait._.html, which then includes the documentation for just one of them.

Hmmm, playing with it a little more I tried using doc(no_inline) on all these, I think that looks better than having the traits inlined as _, maybe if a trait is exported as _ and is exposed elsewhere in the crate documentation it should default to no_inline?

Sounds like a good idea. I'll try to do it *soon*.
