<p>This means, that in addition to <code>a == b</code> and <code>a != b</code> being strict inverses, the equality must
be (for all <code>a</code>, <code>b</code> and <code>c</code>):</p>
<ul>
<li>reflexive: <code>a == a</code>;</li>
<li>symmetric: <code>a == b</code> implies <code>b == a</code>; and</li>
<li>transitive: <code>a == b</code> and <code>b == c</code> implies <code>a == c</code>.</li>
</ul>
<p>This property cannot be checked by the compiler, and therefore <code>Eq</code> implies
<code>PartialEq</code>, and has no extra methods.</p>
<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, because <code>Eq</code> has
no extra methods, it is only informing the compiler that this is an
equivalence relation rather than a partial equivalence relation. Note that
the <code>derive</code> strategy requires all fields are <code>Eq</code>, which isn't
always desired.</p>
<h2 id='how-can-i-implement-eq' class='section-header'><a href='#how-can-i-implement-eq'>How can I implement <code>Eq</code>?</a></h2>

<code>Eq</code>, which has no methods:</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>)
