LL | impl<T> foreign::Trait1<Local, T> for Identity<T> {}
| ^ type parameter `T` must be covered by another type when it appears before the first local type (`Local`)
|
= note: implementing a foreign trait is only possible if at least one of the types for which it is implemented is local, and no uncovered type parameters appear before that first local type
= note: in this case, 'before' refers to the following order: `impl<..> ForeignTrait<T1, ..., Tn> for T0`, where `T0` is the first and `Tn` is the last
