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

| Boost.Hana 1.0.0 Your standard library for metaprogramming |

boost::mpl::integral_c< T, v > Struct Template Reference
External adapters » Boost.MPL adapters

## 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_constant`s are. As a consequence, they are also implicitly a model of the concepts provided for all models of `Constant`.
