Detailed Description

template<typename T>
struct rpnx::querygraph::hasher< T >

Hash a value for use as a QueryGraph memoization key.

Most values are hashed through rpnx::serial4::hash, keeping the cache key consistent with QueryGraph's serialization model. std::type_index uses its standard-library hash because it represents process-local type identity rather than serialized application data.

Applications may specialize this class template for input types that are not supported by the default serialization hash.

Template Parameters

T	Value type to hash.
