<p>An order is a total order if it is (for all <code>a</code>, <code>b</code> and <code>c</code>):</p>
<ul>
<li>total and antisymmetric: exactly one of <code>a < b</code>, <code>a == b</code> or <code>a > b</code> is true; and</li>
<li>transitive, <code>a < b</code> and <code>b < c</code> implies <code>a < c</code>. The same must hold for both <code>==</code> and <code>></code>.</li>
</ul>
<h2 id='derivable' class='section-header'><a href='#derivable'>Derivable</a></h2>
<p>This trait can be used with <code>#[derive]</code>. When <code>derive</code>d, it will produce a lexicographic
ordering based on the top-to-bottom declaration order of the struct's members.</p>
<h2 id='how-can-i-implement-ord' class='section-header'><a href='#how-can-i-implement-ord'>How can I implement <code>Ord</code>?</a></h2>
<p><code>Ord</code> requires that the type also be <code>PartialOrd</code> and <code>Eq</code> (which requires <code>PartialEq</code>).</p>
<p>Then you must define an implementation for <code>cmp()</code>. You may find it useful to use
<code>cmp()</code> on your type's fields.</p>
<p>Implementations of <code>PartialEq</code>, <code>PartialOrd</code>, and <code>Ord</code> <em>must</em> agree with each other. It's
easy to accidentally make them disagree by deriving some of the traits and manually
implementing others.</p>
<p>Here's an example where you want to sort people by height only, disregarding <code>id</code>
and <code>name</code>:</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>)
