Returns a local value from a function without running the copy constructor

I am trying to remove a copy constructor using the C ++ type system to prevent copying an object.

struct DeleteCopyConstructor {
    DeleteCopyConstructor() {};
    DeleteCopyConstructor(DeleteCopyConstructor& op2) = delete;
    DeleteCopyConstructor(const DeleteCopyConstructor& op2) = delete;
};

DeleteCopyConstructor f() {
    DeleteCopyConstructor d;
    // initialize d...
    return d;
}

      

        
        
        
      

    

Mistake:

error: use of deleted function ‘DeleteCopyConstructor::DeleteCopyConstructor(const DeleteCopyConstructor&)’

      

        
        
        
      

    

I read about copying, but it seems to be a compiler optimization, so I don't think it applies. How can I revert d

without starting a build copy?
