|

<p>A compare-and-set operation can have different memory orderings depending on whether it
|
||
succeeds or fails. This trait generalizes different ways of specifying memory orderings.</p>
|
||
<p>The two ways of specifying orderings for compare-and-set are:</p>
|
||
<ol>
|
||
<li>Just one <code>Ordering</code> for the success case. In case of failure, the strongest appropriate
|
||
ordering is chosen.</li>
|
||
<li>A pair of <code>Ordering</code>s. The first one is for the success case, while the second one is

for the failure case.</li>

<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>)
