error[E0277]: can't compare `SomeNode` with `SomeNode`
|
|
--> $DIR/derive-implicit-bound.rs:25:15
|
|
|
|
|
LL | accept_eq(&node);
|
|
| --------- ^^^^^ no implementation for `SomeNode == SomeNode`
|
|
| |
|
|
| required by a bound introduced by this call
|
|
|
|
|
= help: the trait `PartialEq` is not implemented for `SomeNode`
|
|
note: required for `Id<SomeNode>` to implement `PartialEq`
|
|
--> $DIR/derive-implicit-bound.rs:6:12
|
|
|
|
|
LL | #[derive(PartialEq, Eq)]
|
|
| --------- in this derive macro expansion
|
|
LL | pub struct Id<T>(PhantomData<T>);
|
|
| ^^ - type parameter would need to implement `PartialEq`
|
|
= help: consider manually implementing `PartialEq` to avoid undesired bounds
|
|
note: required by a bound in `accept_eq`
|
|
--> $DIR/derive-implicit-bound.rs:17:23
|
|
|
|
|
LL | fn accept_eq(_: &impl PartialEq) { }
|
|
| ^^^^^^^^^ required by this bound in `accept_eq`
|
|
help: consider annotating `SomeNode` with `#[derive(PartialEq)]`
|
|
|
|
|
LL + #[derive(PartialEq)]
|
|
LL | struct SomeNode();
