  12    |                 `iter` escapes the function body here
  13    |                 argument requires that `'1` must outlive `'static`
  14    |
  15    = note: requirement occurs because of a mutable reference to `Eat<&mut I, F>`
  16    = note: mutable references are invariant over their type parameter
  17    = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
  18    = note: due to current limitations in the borrow checker, this implies a `'static` lifetime
