…(that is if it can't move an object and there is not restriction mechanism in a constructor) - it will be used as a copy constructor which is expensive. I will advice you to read Nicolai Josuttis' " C++ Move Semantics - The Complete Guide" [1] which describes in great detail all the tips and tricks around move semantics. P.S.: For any C++ developer out there, in my humble opinion anything written by Nicolai Josuttis is a must-read! [1]…
……（也就是说如果它不能 move 某个对象，而且构造函数里没有限制机制的话）——它就会被当成 copy constructor 用，开销非常大。我建议你读一下 Nicolai Josuttis 的《C++ Move Semantics - The Complete Guide》[1]，里面极其详尽地讲了 move semantics 的各种技巧和门道。P.S.：对所有 C++ 开发者来说，依拙见，Nicolai Josuttis 写的任何东西都是必读的！[1]……
