Detailed Description

An empty class that can't be copied nor moved.

---

A class derived from this one can still be copied (or moved) with an explicit effort. For example, to enable copy construction:

struct CopiableClass: protected UncopiableAndUnmovableClass {
  CopiableClass(CopiableClass const& from)
    : UncopiableAndUnmovableClass() // , ...
    {
      // ...
    }
};

the default constructor of the base class can be called explicitly instead of the copy constructor. To provide an assignment operation,

struct MoveAssignableClass: protected UncopiableAndUnmovableClass {
  MoveAssignableClass& operator= (MoveAssignableClass&& from)
    {
      // ...
      return *this;
    }
};
