The output iterator std::raw_storage_iterator makes it possible for standard algorithms to store results in uninitialized memory. Whenever the algorithm writes an object of type T to the dereferenced iterator, the object is copy-constructed into the location in the uninitialized storage pointed to by the iterator. The template parameter OutputIterator is any type that satisfied output iterator requirements and has Template:cpp defined to return an object, for which Template:cpp returns an object of type T*. Usually, the type T* is used as OutputIterator.
