   1 error[E0277]: the size for values of type `X` cannot be known at compilation time

   7    |      this type parameter needs to be `std::marker::Sized`

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

  20    |           this could be changed to `Y: ?Sized`...
  21 help: consider removing the `?Sized` bound to make the type parameter `Sized`
