22.11 Class type_­index [type.index]

22.11.3 type_­index members [type.index.members]

type_index(const type_info& rhs) noexcept;
Effects: Constructs a type_­index object, the equivalent of target = &rhs.
bool operator==(const type_index& rhs) const noexcept;
Returns: *target == *rhs.target.
bool operator<(const type_index& rhs) const noexcept;
Returns: target->before(*rhs.target).
bool operator>(const type_index& rhs) const noexcept;
Returns: rhs.target->before(*target).
bool operator<=(const type_index& rhs) const noexcept;
Returns: !rhs.target->before(*target).
bool operator>=(const type_index& rhs) const noexcept;
Returns: !target->before(*rhs.target).
strong_ordering operator<=>(const type_index& rhs) const noexcept;
Effects: Equivalent to: if (*target == *rhs.target) return strong_ordering::equal; if (target->before(*rhs.target)) return strong_ordering::less; return strong_ordering::greater;
size_t hash_code() const noexcept;
Returns: target->hash_­code().
const char* name() const noexcept;
Returns: target->name().
