タイプstd::allocator_arg_tの最初のパラメータを持っているコンストラクタはallocあるタイプAの第2引数Allocatorを持っている必要があります。このアロケータはfunctionが使用する可能性のあるすべての内部データ構造にメモリを作成するために使用され.

Original:

Constructors that have a first parameter of type std::allocator_arg_t must have a second argument alloc of type A that is an Allocator. This allocator is used to create memory for any internal data structures that the function might use.

5、10）タイプFはCopyConstructibleであるべきであり、オブジェクトfはCallableでなければなりません。 fがNULL関数ポインタ、メンバへのNULLポインターの場合、またはf場合はstd::functionあると!f == trueた場合に作成された関数オブジェクトは空になります。引数fは、得られた関数オブジェクトに移動されます.

Original:

5, 10) The type F should be CopyConstructible and the object f should be Callable. The resulting function object that is created will be empty if f is a NULL function pointer, a NULL pointer to member, or if f is a std::function and !f == true. The argument f is moved into the resulting function object.
