How to use a object whose copy constructor and copy assignment is private?

In reading TCPL, I got a problem, as the title refered, and then 'private' class is: 

class Unique_handle {
private:   
    Unique_handle& operator=(const Unique_handle &rhs);  
    Unique_handle(const Unique_handle &rhs); 
public:
    //...
}

The using code is:

struct Y {
    Unique_handle obj;
};

And I want to do such operations

main()
{
    Y y1;
    Y y2 = y1;
    return 0;
}

although, these code are come from TCPL, but I still can not got the solution... Can anybody help me, appreciate.

Evidently you need "friend" declarations in that class, or that class already has static accessors that will create or even assign the instance you need.
