Variables
template<typename >
constexpr bool	daw::json::anonymous_namespace{daw_json_traits.h}::can_single_allocation_string_v = false
	Can use the fast, pseudo random string iterators. They are InputIterators with an operator- that allows for O(1) distance calculations as we often know the length but cannot provide random access. For types that only use InputIterator operations and last - first for distance calc.
template<typename T >
constexpr bool	daw::json::anonymous_namespace{daw_json_traits.h}::force_aggregate_construction_v
template<typename... Ts>
constexpr bool	daw::json::anonymous_namespace{daw_json_traits.h}::is_empty_pack_v = sizeof...( Ts ) == 0
template<typename T >
constexpr bool	daw::json::anonymous_namespace{daw_json_traits.h}::is_pinned_type_v
	Is the type pinned in memory and unable to be copied/moved after construction(e.g. std::mutex). These types require using RVO in order to be used but that can have a penalty as std::current_exceptions( ) must be checked which is quite noticeable on MSVC.
