<h1 id="safety" class="section-header"><a href="#safety">Safety</a></h1>
<p>Dereferencing a pointer is unsafe because it could be pointing to invalid memory.</p>
<p>Another concern is the possiblity of data races due to lack of proper synchronization.
For example, consider the following scenario:</p>
<ol>
<li>A thread creates a new object: <code>a.store(Owned::new(10), Relaxed)</code></li>
<li>Another thread reads it: <code>*a.load(Relaxed, guard).as_ref().unwrap()</code></li>

<p>The problem is that relaxed orderings don't synchronize initialization of the object with
the read from the second thread. This is a data race. A possible solution would be to use
<code>Release</code> and <code>Acquire</code> orderings.</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>)
