error[E0307]: invalid `self` parameter type: `Bar`

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`)
