Feature request: link to other crates in a workspace

[xxchan]

Some project has many sub-crates, e.g., arrow-rs: https://github.com/apache/arrow-rs / https://docs.rs/arrow/41.0.0/arrow/

Users usually need to browse related crates together, but it's inconvenient to jump between them on docs.rs.

Currently the solution is deploy cargo doc --no-deps --workspace separately e.g., to GitHub Pages.

It would be nice if docs.rs can natively display all crates similarly. Alternatively, maybe allowing the author to specify some metadata for related crates also makes some sense.

@xxchan this seems like a duplicate of #2021, or am I missing something?

Yes, it looks like the same. I searched "workspace" but not found it. 😄
