_ExpanderTraits< SRC, RES > Struct Template Reference

#include "lib/iter-explorer.hpp"

Description

template<class SRC, class RES>
struct lib::anonymous_namespace{iter-explorer.hpp}::_ExpanderTraits< SRC, RES >

helper to derive a suitable common type when expanding children

Template Parameters

SRC	source iterator fed into the Expander
RES	result type of the expansion function

Note

this also implies the decision, if the common result can be exposed by-ref or must be delivered as value, which may have further ramification down the pipeline.
