boost::mpl::integral_c< T, v > Struct Template Reference

Description

template<typename T, T v>
struct boost::mpl::integral_c< T, v >

Adapter for IntegralConstants from the Boost.MPL.

Provided models

  1. Constant and IntegralConstant
    A Boost.MPL IntegralConstant is a model of the IntegralConstant and Constant concepts just like hana::integral_constants are. As a consequence, they are also implicitly a model of the concepts provided for all models of Constant.
