error[E0277]: `()` doesn't implement `std::fmt::Display`
--> $DIR/doesnt-satisfy.rs:9:17
|
LL | fn bar() -> () {}
| ^^ `()` cannot be formatted with the default formatter
|
= help: the trait `std::fmt::Display` is not implemented for `()`
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
note: required by a bound in `Foo::bar::{opaque#0}`
--> $DIR/doesnt-satisfy.rs:5:22

LL | fn bar() -> impl std::fmt::Display;
| ^^^^^^^^^^^^^^^^^ required by this bound in `Foo::bar::{opaque#0}`
error: aborting due to previous error
