error[E0700]: hidden type for `impl Clone` captures lifetime that does not appear in bounds
--> $DIR/arbitrary_self_types_pin_lifetime_impl_trait-async.rs:8:48
|
LL | async fn f(self: Pin<&Self>) -> impl Clone { self }
| ----- ---------- ^^^^^^^^
| | |
| | opaque type defined here
| hidden type `Pin<&Foo>` captures the anonymous lifetime defined here
|
help: to declare that `impl Clone` captures `'_`, you can add an explicit `'_` lifetime bound
|
LL | async fn f(self: Pin<&Self>) -> impl Clone + '_ { self }
