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.
x, y | - | iterators to the elements to swap |
(none).
