error[E0277]: the trait bound `NotCopy: Copy` is not satisfied
--> $DIR/wf-const-type.rs:10:12
|
LL | const FOO: IsCopy<Option<NotCopy>> = IsCopy { t: None };
| ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy`
|
= note: required because of the requirements on the impl of `Copy` for `Option<NotCopy>`
note: required by a bound in `IsCopy`
--> $DIR/wf-const-type.rs:7:17
|
LL | struct IsCopy<T:Copy> { t: T }
| ^^^^ required by this bound in `IsCopy`
help: consider annotating `NotCopy` with `#[derive(Copy)]`
|
LL | #[derive(Copy)]
|
error: aborting due to previous error
