template<std::indirectly_swappable<Iter> Iter2> friendconstexprvoid iter_swap(const move_iterator& x, conststd::move_iterator<Iter2>& y) noexcept(/* see below */);		(since C++20)

Swaps the objects pointed to by two underlying iterators.

Equivalent toranges::iter_swap(x.base(), y.base());.

This function template is not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup whenstd::move_iterator<Iter> is an associated class of the arguments.

[edit]Parameters

x, y

move iterators to the elements to swap

[edit]Complexity

Constant.

[edit]Exceptions

noexcept specification:

noexcept(noexcept(ranges::iter_swap(x.base(), y.base())))

[edit]Example

Run this code

#include <iostream>#include <iterator>#include <string>#include <vector> int main(){std::vector<std::string> p{"AA","EE"},                             q{"ⱯⱯ","ƎƎ"}; std::move_iterator<std::vector<std::string>::iterator>        x=std::make_move_iterator(p.begin()),        y=std::make_move_iterator(q.begin()); std::cout<<*x<<' '<<*y<<'\n';     iter_swap(x, y);// ADL std::cout<<*x<<' '<<*y<<'\n';}

Output:

AA ⱯⱯⱯⱯ AA
