error[E0277]: the trait bound `Inner<T>: Clone` is not satisfied
--> $DIR/tuple-struct-where-clause-suggestion-91520.rs:15:17
|
LL | #[derive(Clone)]
| ----- in this derive macro expansion
LL | struct Outer<T>(Inner<T>);
| ^^^^^^^^ the trait `Clone` is not implemented for `Inner<T>`
|
help: consider annotating `Inner<T>` with `#[derive(Clone)]`
|
LL + #[derive(Clone)]
LL | struct Inner<T>(T);
|
help: consider introducing a `where` clause, but there might be an alternative better way to express this requirement
|
LL | struct Outer<T>(Inner<T>) where Inner<T>: Clone;
