error[E0307]: invalid `self` parameter type: `Bar`
--> $DIR/arbitrary-self-opaque.rs:8:18
|
LL | fn foo(self: Bar) {}
| ^^^
|
= note: type of `self` must be `Self` or a type that dereferences to it
= help: consider changing to `self`, `&self`, `&mut self`, `self: Box<Self>`, `self: Rc<Self>`, `self: Arc<Self>`, or `self: Pin<P>` (where P is one of the previous types except `Self`)
error: item does not constrain `Bar::{opaque#0}`
--> $DIR/arbitrary-self-opaque.rs:8:8

LL | fn foo(self: Bar) {}
| ^^^
|
= note: consider removing `#[define_opaque]` or adding an empty `#[define_opaque()]`
note: this opaque type is supposed to be constrained
