<p>This trait is automatically implemented when the compiler determines it's
appropriate.</p>
<p>An example of a non-<code>Send</code> type is the reference-counting pointer
<a href="../../std/rc/struct.Rc.html"><code>rc::Rc</code></a>. If two threads attempt to clone <a href="../../std/rc/struct.Rc.html"><code>Rc</code></a>s that point to the same
reference-counted value, they might try to update the reference count at the
same time, which is <a href="../../reference/behavior-considered-undefined.html">undefined behavior</a> because <a href="../../std/rc/struct.Rc.html"><code>Rc</code></a> doesn't use atomic
operations. Its cousin <a href="../../std/sync/struct.Arc.html"><code>sync::Arc</code></a> does use atomic operations (incurring
some overhead) and thus is <code>Send</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>)
