that “cargo doc” supports different versions of one crate seems more helpful

Problem

now, if i “cargo doc” higher version of one crate, the html files of lower version generated by “cargo doc” will be erased.

Proposed Solution

cargo doc should support different versions of one crate

Could you add a reproduction case?

Without more information, I'm going to close. If you have more information on your use case and how this would be useful to you, feel free to reopen. However, I suspect general support for this would be blocked on #10241, since we don't have the ability to have arbitrary directory names. I would suggest if you need something that retains multiple versions (like https://docs.rs/ does) that you'll just need to move the directories to a more suitable location.
