= note: partial move occurs because `self.value` has type `std::option::Option<T>`, which does not implement the `Copy` trait
Unlike expr macros, macros in type position in a derive input are rare
enough that it's not worth supporting for an issue that has such an easy
workaround (just replace `Self` in the macro input with your type name).
This usage is fine. It's mirroring trait signatures in syn::visit::Visit.
