# isSuccess `true` when the status code is in the 2xx range. ``` var isSuccess: Bool { get } ``` ## Discussion Classifies `statusCode` against the HTTP-like convention used by Tor’s control protocol: 2xx = success, 4xx/5xx = error, 6xx = asynchronous event. Prefer this over direct `statusCode == 250` comparisons so `251` replies (“command accepted but operation unnecessary”) aren’t treated as errors.
