Detailed Description

Provides a generic hashing utility and interface for hashable types.

This header defines:

• A comprehensive hash function object (hash) with specializations for common types
• A base interface (hashable) for user-defined hashable types
• Integration with std::hash for STL compatibility

Features:

• Implements FNV-1a algorithm for byte data
• Specializations for integral types, pointers, strings, and custom types
• Fallback implementations for trivially copyable types
• Safe nullptr handling
• Hash combination utilities

Note

All hash functions are noexcept and provide basic hash distribution
