Namespaces
namespace	tesseract::common
	Namespace owning boost's hash_is_avalanching, and defined iff boost has the trait at all.

Functions
template<typename Tag >
constexpr std::size_t	tesseract::common::hash_value (const NameId< Tag > &id) noexcept
	ADL hook for boost::hash. Returns the cached id value; no rehash per lookup.
template<typename Tag >
std::size_t	tesseract::common::hash_value (const OrderedIdPair< Tag > &p) noexcept
	ADL hook for boost::hash. Returns the cached combined hash; no rehash per lookup.
