/**
* @brief Callback function invoked when the stream |stream_id| is closed.
* We use this function to know if the response is fully received. Since we just fetch 1 resource in this program, after
* the response is received, we submit GOAWAY and close the session.
* @param[in] session: nghttp2 session.
* @param[in] stream_id: stream id.
* @param[in] error_code: The reason of closure.
* Usually one of :enum:`nghttp2_error_code`, but that is not guaranteed. The stream_user_data, which was specified in
* `nghttp2_submit_request()` or `nghttp2_submit_headers()`, is still available in this function.
* @param[in] user_data: The |user_data| pointer is the third argument passed in to the call to
* `nghttp2_session_client_new()` or `nghttp2_session_server_new()`
* @return The implementation of this function must return 0 if it succeeds.
* If nonzero is returned, it is treated as fatal error and `nghttp2_session_send()`
* and `nghttp2_session_mem_send()` functions immediately return :enum:
* `NGHTTP2_ERR_CALLBACK_FAILURE`.
