[rustdoc] Add new --book-location option to add a link to associated guide and generate it if local by GuillaumeGomez · Pull Request #139769 · rust-lang/rust (original) (raw)

You can give it a try here.

It'll need an FCP before getting merged.

Also I need to add tests when the argument is a path but I'll wait for the feature form to be final before doing it to prevent doing it more than once. 😄
