No. You don't have to add Box everywhere. You do need dynamic storage that is not guaranteed to be known in compile time. Box is just one of them, you can also use "thin box" or "stacked box" or a good ol' "&mut dyn T" would also do great. It basically means a construct of this object with this trait and solved on dynamic dispatch. In C++ that is virtual/pure virtual function. |
