friend constexpr void iter_swap( const /*iterator*/& x, const /*iterator*/& y )     noexcept(/* 见下文 */)         requires (std::indirectly_swappable<ranges::iterator_t<             /*maybe-const*/<Const, Views>>> && ...);		(C++23 起)

对 [​0​, sizeof...(Views)) 中的每个整数 i 实施 ranges::iter_swap(std::get<i>(x.current_), std::get<i>(y.current_)) 其中 current_ 代表底层持有指向所适配视图的元素的迭代器的元组式对象。

此函数对常规的无限定或有限定查找不可见，而只能在 zip_view::iterator<Const> 为实参的关联类时由实参依赖查找找到。

参数

x, y

-

指向要交换元素的迭代器

返回值

（无）
