(移動)型のインスタンスが移動、割り当てることができることを指定します。これは、タイプがmoveセマンティクスを持つことを意味します:つまり、潜在的にオーバーヘッドを最小限に抑え、同じタイプの別のインスタンスに、その内部状態を転送することができます.
Original:
Specifies that an instance of the type can be move-assigned (moved). This means that type has move semantics: that is, can transfer its internal state to another instance of the same type potentially minimizing the overhead.
