error: implementation of `FnOnce` is not general enough
--> $DIR/closure-mismatch.rs:8:5
|
LL | baz(|_| ());
| ^^^^^^^^^^^ implementation of `FnOnce` is not general enough
|
= note: closure with signature `fn(&'2 ())` must implement `FnOnce<(&'1 (),)>`, for any lifetime `'1`...
= note: ...but it actually implements `FnOnce<(&'2 (),)>`, for some specific lifetime `'2`
error[E0308]: mismatched types
--> $DIR/closure-mismatch.rs:8:5
|
LL | baz(|_| ());
| ^^^^^^^^^^^ one type is more general than the other
|
= note: expected trait `for<'r> Fn<(&'r (),)>`
found trait `Fn<(&(),)>`
note: this closure does not fulfill the lifetime requirements
--> $DIR/closure-mismatch.rs:8:9
|
LL | baz(|_| ());
| ^^^
note: the lifetime requirement is introduced here
--> $DIR/closure-mismatch.rs:5:11

LL | fn baz<T: Foo>(_: T) {}
