<pre class='rust struct'>pub struct Keyword(_);</pre><div class='docblock'><p>A keyword is a symbol, optionally with a namespace, that prints with a leading colon.
This concept is imported from Clojure, as it features in EDN and the query
syntax that we use.</p>
<p>Clojure's constraints are looser than ours, allowing empty namespaces or
names:</p>
<pre><code class="language-clojure">user=&gt; (keyword &quot;&quot; &quot;&quot;)
:/
user=&gt; (keyword &quot;foo&quot; &quot;&quot;)
:foo/
user=&gt; (keyword &quot;&quot; &quot;bar&quot;)
:/bar
</code></pre>
<p>We think that's nonsense, so we only allow keywords like <code>:bar</code> and <code>:foo/bar</code>,
with both namespace and main parts containing no whitespace and no colon or slash:</p>

<p>If you're not sure whether your input is well-formed, you should use a
parser or a reader function first to validate. TODO: implement <code>read</code>.</p>
<p>Callers are expected to follow these rules:

<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>)
