（移動）型のインスタンスが移動に構築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、同じタイプの新しいインスタンスに、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-constructed (moved). This means that type has move semantics: that is, can transfer its internal state to a new instance of the same type potentially minimizing the overhead.

Type::Type

Type::Type( Type&& other ); Type::Type( const Type&& other ); Type::Type( volatile Type&& other ); Type::Type( const volatile Type&& other );		(亜種の一つで十分です)

コンストラクタを移動します: constructs an instance of a type with the contents of other. The internal state of other is unspecified after the move. However, it must still be valid, that is, no invariants of the type are broken.

The following expressions must have the specified effects:
