rustdoc: add flag to control the html_root_url of dependencies The `--extern-html-root-url` flag in this PR allows one to override links to crates whose docs are not already available locally in the doc bundle. Docs.rs currently uses a version of this to make sure links to other crates go into that crate's docs.rs page. See the included test for intended use, but the idea is as follows: Calling rustdoc with `--extern-html-root-url crate=https://some-url.com` will cause rustdoc to override links that point to that crate to instead be replaced with a link rooted at `https://some-url.com/`. (e.g. for docs.rs this would be `https://docs.rs/crate/0.1.0` or the like.) Cheekily, rustup could use these options to redirect links to std/core/etc to instead point to locally-downloaded docs, if it so desired. Fixes https://github.com/rust-lang/rust/issues/19603 |
