struct aligned_union;
 (C + + 11以来)
正しくtypeに記載されている任意の型のオブジェクトに整列させた初期化されていないストレージとして使用するのに適したPOD型であるメンバのtypedefTypesは、用意されています。ストレージのサイズは少なくともLenです。 std::aligned_unionはまた、すべてのTypesうち最も厳しい数値（最大）の配置要件を決定し、一定alignment_valueとして使用できるようにします.
Original:
Provides the member typedef type, which is a POD type suitable for use as uninitialized storage, correctly aligned for an object of any of the types listed in Types. The size of the storage is at least Len. std::aligned_union also determines the strictest (largest) alignment requirement among all Types and makes it available as the constant alignment_value.
