<p>Sometimes concurrent programming requires a piece of data to be padded out to the size of a
|
||
cacheline to avoid "false sharing": cache lines being invalidated due to unrelated concurrent
|
||
activity. Use this type when you want to <em>avoid</em> cache locality.</p>

|

<p>By default, the size of <code>CachePadded<T></code> is 64 bytes. If <code>T</code> is larger than that, then
|
||
<code>CachePadded::<T>::new</code> will panic. Alignment of <code>CachePadded<T></code> is the same as that of <code>T</code>.</p>
|
||
<p>However, if the <code>nightly</code> feature is enabled, arbitrarily large types <code>T</code> can be stored inside
|
||
a <code>CachePadded<T></code>. The size will then be a multiple of 64 at least the size of <code>T</code>, and the
|
||
alignment will be the maximum of 64 and the alignment of <code>T</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>)
