Function method_page 

fn method_page<'a>(method: &'a TraitMethod, type_str: &'a str) -> &'a str

The page a trait method’s own block lands on, and with it the companion block that must share it (the S3 generic block, named after the method): the @describeIn destination, the method-level @rdname, else the type’s shared page. Generics of S4 / S7 and consts always use the type page.
