    class type_index;
    template <class T> struct hash;
    template<> struct hash<type_index>;
}

Class std::type_index

    bool operator!=(const type_index& rhs) const noexcept;

    bool operator<= (const type_index& rhs) const noexcept;
    bool operator> (const type_index& rhs) const noexcept;

    size_t hash_code() const;
    const char* name() const;
private:
    const type_info* target; // exposition only
    // Note that the use of a pointer here, rather than a reference,
    // means that the default copy/move constructor and assignment
    // operators will be provided and work as expected.
