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

Swaps the objects pointed to by two underlying iterators (denoted as inner_).

Equivalent to: ranges::iter_swap(x.inner_, y.inner_);.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `join_view::iterator<Const>` is an associated class of the arguments.

### Parameters

x, y | - | iterators

### Return value

(none)

### Exceptions

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