Correct use of `= delete` for methods in classes

Question

Is the following snipplet correct for un-defining all otherwise generated methods and constructors for a class?

struct Picture {

  // \'explicit\': no accidenta         


        

Answer 1

Seems fine to me. The return value of operator= must be a normal reference, even if the object is constructed from a rvalue reference. That is because you can't just compile an lvalue (*this) to an rvalue.
And it should take that rvalue reference per non-const Picture& operator=(Picture&&). How would you move from a constant object? ;)
