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。
