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>>; |  | (since C++23)

Applies ranges::iter_swap to the underlying cached iterators.

Let `parent_` be the underlying pointer to the enclosing `chunk_view`, and *i.parent_->current_ denote the underlying cached iterator of type ranges::iterator_t<V>.

Equivalent to: ranges::iter_swap(*x.parent_->current_, *y.parent_->current_);.

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

### Parameters

x, y | - | iterators to the elements to swap

### Return value

(none)

### See also

iter_swap (C++20) | swaps the values referenced by two dereferenceable objects (customization point object)
iter_swap | swaps the elements pointed to by two iterators (function template)
