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.

(none).

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

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