template<typename T, T v>
struct boost::mpl::integral_c< T, v >
Adapter for IntegralConstants from the Boost.MPL. 
Provided models 
- Constantand- IntegralConstant
 A Boost.MPL IntegralConstant is a model of the- IntegralConstantand- Constantconcepts just like- hana::integral_constants are. As a consequence, they are also implicitly a model of the concepts provided for all models of- Constant.- #include <boost/mpl/int.hpp> - #include <boost/mpl/long.hpp> - namespace mpl = boost::mpl; - static_assert( hana::value- (mpl::integral_c<int, 3>{}) == 3,  ""- ); 
- int main() { }
