error: item does not constrain `Foo::{opaque#0}`, but has it in its signature
--> $DIR/nested.rs:10:4
|
LL | fn bar() -> Bar {
| ^^^
|
= note: consider moving the opaque type's declaration and defining uses into a separate module
note: this opaque type is in the signature
--> $DIR/nested.rs:3:12
|
LL | type Foo = impl std::fmt::Debug;
| ^^^^^^^^^^^^^^^^^^^^
error[E0277]: `Bar` doesn't implement `Debug`
--> $DIR/nested.rs:16:22
|
LL | println!("{:?}", bar());
| ^^^^^ `Bar` cannot be formatted using `{:?}` because it doesn't implement `Debug`
|
= help: the trait `Debug` is not implemented for `Bar`
= note: this error originates in the macro `$crate::format_args_nl` which comes from the expansion of the macro `println` (in Nightly builds, run with -Z macro-backtrace for more info)
error: aborting due to 2 previous errors
