10 | = help: the trait `Sized` is not implemented for `dyn for<'r> Fn(&'r isize) -> isize` |
11 | help: you could relax the implicit `Sized` bound on `T` if it were used through indirection like `&T` or `Box<T>` | |

14 | LL | enum Option<T> { | |
15 | | ^ this could be changed to `T: ?Sized`... | |
16 | LL | Some(T), | |
17 | | - ...if indirection was used here: `Box<T>` | |
