friend constexpr void iter_swap( const /*iterator*/ & x, const /*iterator*/ & y )

noexcept( /*see below*/ )

        requires std::indirectly_swappable < ranges::iterator_t <Base>> ;
(since C++23)

Swaps the objects pointed to by two underlying arrays of iterators (denoted as current_).

Equivalent to:

for (std::size_t i{}; i != N; ++i)
{
    std::ranges::iter_swap(x.current_[i], y.current_[i]);
}

The behavior is undefined if before the operation none of the iterators in x.current_ is equal to an iterator in y.current_

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when adjacent_view::iterator<Const>

Parameters

x, y - iterators

Return value

(none)

Exceptions

noexcept specification:  
noexcept (std:: ranges::iter_swap (declval< ranges::iterator_t <Base>> ( ),
                                declval< ranges::iterator_t <Base>> ( ) ) )
