broken links in docs for String

[lorepozo]

All String methods which come from the borrowed &str have broken links. e.g. char in std::string::String::chars (which is basically std::str::chars).

I'd fix it myself, but I'm not sure what the approach should be so that both docs pages, for String and for the primitive str, would work. Maybe there's a planned rustdoc feature which could help resolve this?

This is a duplicate of #32130; thank you for filing! It's a tricky bug, and we're not 100% sure how to solve it yet. https://github.com/rust-lang/rfcs/blob/master/text/1946-intra-rustdoc-links.md will probably fix it, we'll see!
