> * If we use direct setting of fields, we can avoid the extra temporary buffer and memcpy by setting bytes directly.
>  * We should overwrite existing vectors in consumers before returning results, to avoid the possibility of closing vectors in use (or alternatively make sure we retain the underlying buffers).
>  * Try to eliminate some of the state in load() by moving initialization to the constructor.
