callback taking a <code>ServerRequest</code> and returning a <code>Response</code>) which is run on all received
requests.</p>
<p>The <code>handle_next</code> method needs to be called regularly in order to have the server process
received frames, as well as send out the responses.</p>
<p>This is an exceedingly simple implementation of an HTTP/2 server and is mostly an example of
how the <code>solicit::http</code> API can be used to make one.</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>)
