|
||
<p>The <code>T</code> parameter is used for the I/O object used to communicate, which is
|
||
supplied in <code>bind_transport</code>.</p>
|
||
<p>For simple protocols, the <code>Self</code> type is often a unit struct. In more
|
||
advanced cases, <code>Self</code> may contain configuration information that is used
|
||
for setting up the transport in <code>bind_transport</code>.</p>

<h2 id="considerations" class="section-header"><a href="#considerations">Considerations</a></h2>
|
||
<p>There are some difficulties with implementing back pressure in the case
|
||
that the wire protocol does not support a means by which backpressure can
|
||
be signaled to the peer.</p>
|
||
<p>The problem is the potential for deadlock:</p>
|
||
<ul>
|
||
<li>
|
||
<p>The server is busy processing requests on this connection, and stops
|
||
reading frames from its transport.</p>
|
||
</li>
|
||
<li>
|
||
<p>Meanwhile, the processing logic is blocked waiting for another frame that
|
||
is currently pending on the socket.</p>
|
||
</li>
|
||
</ul>
|
||
<p>To deal with this, once the connection's frame buffer is filled, a timeout
|
||
is set. If no further frames are able to be read before the timeout expires,
|
||
the connection is killed.</p>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
