Auto merge of #30342 - salty-horse:doc_links, r=steveklabnik

Many of the structs in `str` that are used as part of its methods do not have links to the methods.
This is especially annoying when a Google search drops you into the documentation of the struct, when you really wanted to get to the method of the same name.

This patch adds those links.
