| | returning this value requires that `'a` must outlive `'static` |
| | requirement occurs due to copying this value |
| | |
| = note: requirement occurs because of the type `Foo<'_>`, which makes the generic argument `'_` invariant |
| = note: the struct `Foo<'a>` is invariant over the parameter `'a` |
