make_move_iterator is a convenience function template that constructs a std::move_iterator for the given iterator i with the type deduced from the type of the argument.
std::move_iterator<Iter>(std::move(i))
[edit] Example#include <iomanip>
#include <iostream>
#include <iterator>
#include <list>
#include <string>
#include <vector>
auto print = [](const auto rem, const auto& seq)
{
for (std::cout << rem; const auto& str : seq)
std::cout << std::quoted(str) << ' ';
std::cout << '\n';
};
int main()
{
std::list<std::string> s{"one", "two", "three"};
std::vector<std::string> v1(s.begin(), s.end()); // copy
std::vector<std::string> v2(std::make_move_iterator(s.begin()),
std::make_move_iterator(s.end())); // move
print("v1 now holds: ", v1);
print("v2 now holds: ", v2);
print("original list now holds: ", s);
}
Possible output:
v1 now holds: "one" "two" "three" v2 now holds: "one" "two" "three" original list now holds: "" "" ""[edit] Defect reports
