| error: lifetime may not live long enough |

| | -- lifetime `'a` defined here |
| LL | let unsend: *const dyn Cat<'a> = &(); |
| LL | let _send = unsend as *const S<dyn Cat<'static>>; |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^ type annotation requires that `'a` must outlive `'static` |
| | |
| = note: requirement occurs because of the type `S<dyn Cat<'_>>`, which makes the generic argument `dyn Cat<'_>` invariant |
| = note: the struct `S<T>` is invariant over the parameter `T` |
