   |                       cannot move out of here
   |                       move occurs because `drop_struct.fancy` has type `FancyNum`, which does not implement the `Copy` trait
   |
note: if `FancyNum` implemented `Clone`, you could clone the value

LL | struct FancyNum {

help: consider borrowing here
