error[E0277]: `T` doesn't implement `Debug`

LL | type Two<T, U> = impl Debug;
   |                  ^^^^^^^^^^ `T` cannot be formatted using `{:?}` because it doesn't implement `Debug`
   |
   = note: required because of the requirements on the impl of `Debug` for `(T, T)`
help: consider restricting type parameter `T`

LL | type Two<T: Debug, U> = impl Debug;
   |           ^^^^^^^
