Constraints: x.base() == y.base() is well-formed and convertible to bool.

Returns: x.base() == y.base().
🔗
template<class Iterator1, class Iterator2> constexpr bool operator!=( const reverse_iterator<Iterator1>& x, const reverse_iterator<Iterator2>& y);
3
#
Constraints: x.base() != y.base() is well-formed and convertible to bool.

#
Returns: x.base() != y.base().
🔗

7
#
Constraints: x.base() < y.base() is well-formed and convertible to bool.
8
#
Returns: x.base() < y.base().
🔗
template<class Iterator1, class Iterator2> constexpr bool operator<=( const reverse_iterator<Iterator1>& x, const reverse_iterator<Iterator2>& y);
9
#
Constraints: x.base() >= y.base() is well-formed and convertible to bool.
10
#
Returns: x.base() >= y.base().
🔗
template<class Iterator1, class Iterator2> constexpr bool operator>=( const reverse_iterator<Iterator1>& x, const reverse_iterator<Iterator2>& y);
11
#
Constraints: x.base() <= y.base() is well-formed and convertible to bool.
12
#
Returns: x.base() <= y.base().
🔗
template<class Iterator1, three_way_comparable_with<Iterator1> Iterator2> constexpr compare_three_way_result_t<Iterator1, Iterator2> operator<=>(const reverse_iterator<Iterator1>& x, const reverse_iterator<Iterator2>& y);

[Note 1: 
The argument order in the Returns: element is reversed because this is a reverse iterator.
