+error[E0521]: borrowed data escapes outside of function
+ --> $DIR/hrtb-implied-2.rs:18:17
+ |
+LL | fn fails<I: LendingIterator, F>(iter: &mut I, f: F) -> bool
+ | ---- - let's call the lifetime of this reference `'1`
+ | |
+ | `iter` is a reference that is only valid in the function body
+...
+LL | let _next = iter2.next();
+ | ^^^^^^^^^^^^
+ | |
+ | `iter` escapes the function body here
+ | argument requires that `'1` must outlive `'static`
+ |
+ = note: requirement occurs because of a mutable reference to `Eat<&mut I, F>`
+ = note: mutable references are invariant over their type parameter
+ = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
+ = note: due to current limitations in the borrow checker, this implies a `'static` lifetime
+
+error: aborting due to previous error
+
+For more information about this error, try `rustc --explain E0521`.
