nostr:npub170qkgyc4v75s6rvkax0sfm6r9watf48zpz5a6fcv0eh9tsw4e5qq5rzcqm I use the local docs for the standard library (I have the tab open right now) because it opens the version that match the version of rust you're using in the project you run the command from.

As for online docs, yeah I dunno 😅 although in this specific instance I was poking around the docs of a crate in order to link to them in a comment, so needed the online URL.
