template<typename T, T v>
struct std::integral_constant< T, v >

Adapter for std::integral_constants.

Provided models

  1. Constant and IntegralConstant
    A std::integral_constant 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.
