boost::histogram::axis::traits::is_reducible — Meta-function to detect whether an axis is reducible.
// In header: <boost/histogram/axis/traits.hpp> template<typename Axis> struct is_reducible { };
Doxygen does not render this well. This is a meta-function, it accepts an axis type and represents std::true_type or std::false_type, depending on whether the axis can be reduced with boost::histogram::algorithm::reduce().
typename Axis
axis type.
