Esteban Küber	d68f2a6b71	Mention when type parameter could be `Clone` ... ``` error[E0382]: use of moved value: `t` --> $DIR/use_of_moved_value_copy_suggestions.rs:7:9 | LL | fn duplicate_t<T>(t: T) -> (T, T) { | - move occurs because `t` has type `T`, which does not implement the `Copy` trait ... LL | (t, t) | - ^ value used here after move | | | value moved here | help: if `T` implemented `Clone`, you could clone the value --> $DIR/use_of_moved_value_copy_suggestions.rs:4:16 | LL | fn duplicate_t<T>(t: T) -> (T, T) { | ^ consider constraining this type parameter with `Clone` ... LL | (t, t) | - you could clone this value help: consider restricting type parameter `T` | LL | fn duplicate_t<T: Copy>(t: T) -> (T, T) { | ++++++ ``` The `help` is new. On ADTs, we also extend the output with span labels: ``` error[E0507]: cannot move out of static item `FOO` --> $DIR/issue-17718-static-move.rs:6:14 | LL | let _a = FOO; | ^^^ move occurs because `FOO` has type `Foo`, which does not implement the `Copy` trait | note: if `Foo` implemented `Clone`, you could clone the value --> $DIR/issue-17718-static-move.rs:1:1 | LL | struct Foo; | ^^^^^^^^^^ consider implementing `Clone` for this type ...
