            Move-assign a ip::basic_resolver from another.
          
template< typename Executor1> constraint_t< is_convertible< Executor1, Executor >::value, basic_resolver & > operator=( basic_resolver< InternetProtocol, Executor1 > && other);
This assignment operator moves a resolver from one object to another. Cancels any outstanding asynchronous operations associated with the target object.
                  The other ip::basic_resolver object
                  from which the move will occur.
                
            Following the move, the moved-from object is in the same state as if
            constructed using the basic_resolver(const executor_type&)
            constructor.
