Is there anything that needs to be done or discussed before this can be merged?

The problem with this PR is that it doesn't take into account the version of the std used when documenting the crate. Could you update the url to match it like https://doc.rust-lang.org/{version}/std/ please? So for example: https://doc.rust-lang.org/1.29.0/std/.

When documenting which crate? I'm not sure I understand your comment. I just want docs.rs/std to redirect to the latest std documentation at doc.rust-lang.org/std, because the first url is easier to remember and type. All generated documentation would still directly link to doc.rust-lang.org/{version}/....

From what I understand of your code, it doesn't take the version into account. For example, if the item being linked doesn't exist anymore in the current std lib, then you'd end up with a dead link.

Which items? All it does is redirect docs.rs/std to doc.rust-lang.org/std, nothing else. It doesn't link to specific items.

[GuillaumeGomez]

Oh my bad, I completely misunderstood what your PR was doing... Just one thing then, can you replace the current url with doc.rust-lang.org/stable/std please?

[m-ou-se]

Sure, done!

Ok, looks all good to me now. I'll let @pietroalbini handle the merge. :)

The redirect is in place! https://docs.rs/std
