BOOST_CLASS_TEMPLATE_VERSION

#define BOOST_CLASS_TEMPLATE_VERSION	(		Template,
			Type,
			Version
	)

Value:

  namespace boost {                                           \
    namespace serialization {                                 \
      template<Template>                                      \
      struct version<Type> {                                  \
        static constexpr unsigned int value = Version;        \
      };                                                      \
      template<Template>                                      \
      constexpr unsigned int version<Type>::value;            \
    }                                                         \
  }

Versioning for template classes.

BOOST_CLASS_VERSION does not support templated classes by default. This macro behaves very similarly, except that it accepts a third parameter Template.

BOOST_CLASS_TEMPLATE_VERSION(Rank rank, Tensor<rank>, Tensor<rank>::version)
