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> is an associated class of the arguments.

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 >> ( ) ) )
