An opaque object representing a hash code.
This object represents the result of hashing some entity. It is intended to be used to implement hashtables or other hashing-based data structures. While it wraps and exposes a numeric value, this value should not be trusted to be stable or predictable across processes or executions.
In order to obtain the hash_code for an object 'x':

Note that this leaves the value uninitialized.
