This should just be Self. "SelfTy" is not a keyword.

The doc page cannot be https://doc.rust-lang.org/nightly/std/keyword.Self.html on a case-insensitive host because that will conflict with https://doc.rust-lang.org/nightly/std/keyword.self.html.

IMHO: the ideal would be https://doc.rust-lang.org/nightly/std/keyword.Self%20(type).html as the URL, and to properly display the keyword as Self.

https://doc.rust-lang.org/nightly/std/keyword.SelfTy.html
