error[E0277]: the size for values of type `dyn for<'a> Fn(&'a isize) -> isize` cannot be known at compilation time

= help: the trait `Sized` is not implemented for `dyn for<'a> Fn(&'a isize) -> isize`

note: required by a bound in `Option`

help: you could relax the implicit `Sized` bound on `T` if it were used through indirection like `&T` or `Box<T>`
