error[E0277]: `U` doesn't implement `std::fmt::Debug`
--> $DIR/derive-debug.rs:11:36

| ^^^^^^^^^^^^^^^^^^^^^^ `U` cannot be formatted using `{:?}` because it doesn't implement `std::fmt::Debug`
|
= help: the trait `std::fmt::Debug` is not implemented for `U`
= note: required because of the requirements on the impl of `std::fmt::Debug` for `&U`
= note: required by `std::fmt::Debug::fmt`
