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

    noexcept(/* see below */)
    requires (std::indirectly_swappable<ranges::iterator_t<

      /*maybe-const*/<Const, Views>>> && ...);
(since C++23)

Performs ranges::iter_swap(std::get<i>(x.current_), std::get<i>(y.current_)) for every integer i in [0, sizeof...(Views)), where current_ denotes the underlying tuple-like object that holds iterators to elements of adapted views.

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

Parameters

x, y - iterators to the elements to swap

Return value

(none)

Exceptions

noexcept specification:  
noexcept(

  (noexcept(ranges::iter_swap(
    declval<const ranges::iterator_t</*maybe-const*/<Const, Views>>&>(),

    declval<const ranges::iterator_t</*maybe-const*/<Const, Views>>&>())) &&...))
