| | ^^^^^^^ argument requires that `'a` must outlive `'b` |
| | |
| = help: consider adding the following bound: `'a: 'b` |
| = note: requirement occurs because of the type `Cell<&()>`, which makes the generic argument `&()` invariant |
| = note: the struct `Cell<T>` is invariant over the parameter `T` |
