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

type_index operators

Compares the type_index object to rhs.

For the equality and non-equality comparisons (== and !=), the function uses the same operator directly on the type_info object they refer (see type_info::operator==).

For the other relational operators, the function uses type_info::before to determine their relative order.

Note also that the assignment operator is implicitly declared, copying the internal reference kept by the object.
