struct LocallyHashedType

Declaration

struct LocallyHashedType { /* full declaration omitted */ };

Description

A locally hashed type represents a straightforward hash code of a serialized record. The record is simply serialized, and then the bytes are hashed by a standard algorithm. This is sufficient for the case of de-duplicating records within a single sequence of types, because if two records both have a back-reference to the same type in the same stream, they will both have the same numeric value for the TypeIndex of the back reference.
