| <p>This trait is used when constructing an instance of <a href="struct.Framed.html"><code>Framed</code></a> or |
| <a href="struct.FramedRead.html"><code>FramedRead</code></a>. An implementation of <code>Decoder</code> takes a byte stream that has |
| already been buffered in <code>src</code> and decodes the data into a stream of |
| <code>Self::Item</code> frames.</p> |
| <p>Implementations are able to track state on <code>self</code>, which enables |
| implementing stateful streaming parsers. In many cases, though, this type |
| will simply be a unit struct (e.g. <code>struct HttpDecoder</code>).</p> |
| <p>For some underlying data-sources, namely files and FIFOs, |
| it’s possible to temporarily read 0 bytes by reaching EOF.</p> |
| <p>In these cases <code>decode_eof</code> will be called until it signals |
| fulfillment of all closing frames by returning <code>Ok(None)</code>. |
| After that, repeated attempts to read from the <a href="struct.Framed.html"><code>Framed</code></a> or <a href="struct.FramedRead.html"><code>FramedRead</code></a> |
| will not invoke <code>decode</code> or <code>decode_eof</code> again, until data can be read |
| during a retry.</p> |
| <p>It is up to the Decoder to keep track of a restart after an EOF, |
| and to decide how to handle such an event by, for example, |
| allowing frames to cross EOF boundaries, re-emitting opening frames, or |
| resetting the entire internal state.</p> |

| this instance of <code>Decode</code> can determine whether an entire frame is in |
| the buffer and is ready to be returned.</p> |
| <p>If an entire frame is available, then this instance will remove those |
