friend constexpr void iter_swap( const /*inner-iterator*/& x,                                  const /*inner-iterator*/& y )     noexcept(noexcept(ranges::iter_swap(*x.parent_->current_,                                         *y.parent_->current_)))     requires std::indirectly_swappable<ranges::iterator_t<V>>;		(自 C++23 起)

将 ranges::iter_swap 应用于底层缓存的迭代器。

令 parent_ 为指向封闭 chunk_view 的底层指针，并且 *i.parent_->current_ 表示类型为 ranges::iterator_t<V> 的底层缓存迭代器。

等效于：ranges::iter_swap(*x.parent_->current_, *y.parent_->current_);.

此函数对普通的 非限定 或 限定查找 不可見，并且仅在 依赖于参数的查找 中，当 chunk_view::inner-iterator 是参数的关联类时才可找到。

参数
