Detailed Description

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':

   using llvm::hash_value;
   llvm::hash_code code = hash_value(x);
