A simple streaming operator for the histogram type.
The text representation is rudimentary and not guaranteed to be stable between versions of Boost.Histogram. This header is not included by any other header and must be explicitly included to use the streaming operator.
To use your own, simply include your own implementation instead of this header.
namespace boost { namespace histogram { template<typename T> struct sample_type; template<class... Ts> auto sample(Ts &&...); } }
Headers from Boost.Serialization needed to serialize STL types that are used internally by the Boost.Histogram classes.
