// Rule of three: When a class requires either
//  - a custom destructor
//  - or a copy constructor
//  - or an assignment operator
// it most likely requires all three
class Class {
public:
    Class() {}
    ~Class() { ... }		                // Custom destructor
  
    Class(const Class& c) { ... }	        // Custom copy constructor
  	void operator=(const Class& c) { ... }  // Custom assignment operator
private:
    some_type* non_copyable_resource = nullptr;
}
