This is necessary for bookkeeping when creating new streams. Correct framing requires that stream IDs are sequential on the socket, so we need to bundle assigning the ID with sending the `SYN_STREAM` frame.

Перевага використання `генерації` (raise) помилки замість `повернення` значення (return) стане більш очевидним в розділі про Залежності та Безпеку.

У цьому прикладі, якщо клієнт запитує елемент за ID, якого не існує, буде згенеровано помилку зі статус-кодом `404`:
