error[E0307]: invalid `self` parameter type: `T`
--> $DIR/issue-66312.rs:4:22
|
LL | fn is_some(self: T);
| ^

= 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[E0308]: mismatched types
--> $DIR/issue-66312.rs:9:8

LL | if x.is_some() {
| ^^^^^^^^^^^ expected `bool`, found `()`
error: aborting due to 2 previous errors
