Detailed Description

Class for computing a hash of multiple types, going through GetTypeHash when the type implements it, and fallbacks to raw data hashing when the type doesn't.

Note: this hash builder should be used for transient hashes, as some types implements run-dependent hash computations, such as GetTypeHash(FName).
