friend constexpr void iter_swap( const /*iterator*/& x, const /*iterator*/& y )     noexcept( /*see below*/ )         requires std::indirectly_swappable<InnerIter>;		(自 C++20 起)

交换两个底层迭代器（表示为 inner_）指向的对象。

等效于： ranges::iter_swap(x.inner_, y.inner_);.

此函数对普通 非限定 或 限定查找 不可見，只有在 join_view::iterator<Const> 是参数的关联类时，才能通过 依赖于参数的查找 找到它。

参数

x, y

返回值

noexcept 规范：  

noexcept(noexcept(ranges::iter_swap(x.inner_, y.inner_)))
