Upon success, a positive return value indicates 53 that the parser made forward progress, consuming that number of bytes. 54 In some cases there may be an insufficient number of octets in the input 55 buffer in order to make forward progress. This is indicated by the code 56 <a class="link" href="../boost__beast__http__error.html" title="http::error"><code class="computeroutput"><span class="identifier">error</span><span class="special">::</span><span class="identifier">need_more</span></code></a>. 57 When this happens, the caller should place additional bytes into the buffer 58 sequence and call <a class="link" href="put.html" title="http::basic_parser::put"><code class="computeroutput"><span class="identifier">put</span></code></a> again.
