比较 basic_const_iterator 和另一个值。

!= 运算符从 operator== 运算符合成。

当 std::same_as<I, basic_const_iterator<Iter>> 为 false 时 I 满足 /*different-from*/<basic_const_iterator>。

参数

s	-	Iter 的哨位
y	-	要与之比较的值

返回值

1) base() == s

2) base() < y.base()

3) base() > y.base()

4) base() <= y.base()

5) base() >= y.base()

6) base() <=> y.base()

7) base() < y

8) base() > y

9) base() <= y

10) base() >= y

11) base() <=> y

注解

当 Iter 实现了 sentinel_for<Iter> 时，重载 (1) 可用于比较两个 basic_const_iterator<Iter> 值。
