What does this C++ snippet output?

1#include <iostream>
2#include <vector>
3struct M {
4  M() { std::cout << "ctor\n"; }
5  M(M&&) noexcept { std::cout << "move\n"; }
6  M(const M&) { std::cout << "copy\n"; }
7  ~M() { std::cout << "dtor\n"; }
8};
9int main() {
10    std::vector<M> v;
11    v.reserve(2);
12    v.push_back(M{});
13    std::cout << "one\n";
14}
