operator==(chunk_by_view::iterator)

 

friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y );	(1)	(since C++23)
friend constexpr bool operator==( const /*iterator*/& x, std::default_sentinel_t );	(2)	(since C++23)

比较底层的迭代器。

1) 等价于 return x.current_ == y.current_;.

2) 等价于 return x.current_ == x.next_;.

此函数对于普通的非限定或限定查找不可见，并且只有当 std::ranges::chunk_by_view::iterator 是参数的关联类时，才能通过实参依赖查找找到。

!= 运算符是从 operator== 合成而来的。
