| <p>Error codes are used in <code>RST_STREAM</code> and <code>GOAWAY</code> frames to convey the |
| reasons for the stream or connection error. For example, |
| <a href="struct.SendStream.html#method.send_reset"><code>SendStream::send_reset</code></a> takes a <code>Reason</code> argument. Also, the <code>Error</code> type |
| may contain a <code>Reason</code>.</p> |

| streams, others apply only to connections, and others may apply to either. |
