rustdoc is confusing for `use Foo as Bar` types

[nathan-at-least]

While examining API docs for ipfs_api_backend_hyper::IpfsClient I was confused about the relationship between the symbol IpfsClient and HyperBackend:

I knew that rustdoc explicitly annotates type aliases, but that wasn't what I was seeing, so I fetched the code to examine and find a statement similar to use my_path::HyperBackend as IpfsClient. Ok, but could rustdoc have helped me know this was happening?

I expected to see this happen:

I hope to see some explicit indication that the two symbols refer to the same item. The actual approach might be tricky to get right in a manner that is explicit but not too much clutter.

I've seen rustdoc explicitly annotate that when re-exporting across crate boundaries. Is there some way to do this for intra-crate renaming re-exports so that the crate-level doc would move IpfsClient out of the structs section and into a re-exports section with a crate-local path? It currently looks like this:

With this proposed approach, the rendering for the type interface would consistently use HyperBackend.

I searched this issue tracker with is:issue is:open use as label:A-rustdoc-ui to find these tickets both of which rename to _ which is distinct from my issue:

• Rustdoc doesn't play well with use ... as _ syntax #97615
• Funky rustdoc behavior when pub use path_to::Trait as _; for public-in-private item #92379

I filed this PR against rust-ipfs-api which replaces use foo as bar with explicit type aliases as a work-around. That PR has more screenshots of the difference in doc rendering between the two approaches.
