Documentation: When are type aliases required?

[cryslith]

For instance, the github example requires type URI = String; or else a rather cryptic error like

error[E0412]: cannot find type `URI` in module `super`
   |
   | #[derive(GraphQLQuery)]
   |          ^^^^^^^^^^^^ not found in `super`
   |
   = note: possible candidate is found in another module, you can import it into scope:
           crate::repo_view::URI

is raised at compile time. It would be nice if the documentation mentioned this error message somewhere and explained how to solve it by defining an appropriate type alias.

Definitely!
