*std::*\ swap (:ref:`py::builtins::range <py-builtins-range>`) (specialization)
===============================================================================

.. code-block:: cpp

     template <class type>
     constexpr void swap(
         py::builtins::range<type>& lhs,
         py::builtins::range<type>& rhs
     ) noexcept(noexcept(lhs.swap(rhs)));

Swaps a range with another range.

.. tip::

     Equivalent to::

         lhs.swap(rhs);


Parameter
---------

``lhs``: A range.

``rhs``: Another range.


Complexity
----------

Constant.


Example
-------

.. code-block:: cpp

     #include <pypp/builtins/range.hpp>
     #include <pypp/builtins/print.hpp>

     int main()
     {
         py::range<int> nums1(1, 10);
         py::range<int> nums2(5);

         std::swap(nums1, nums2);
         py::print(nums1.stop());
     }
