<p>This wrapper is 0-cost.</p>
<p><code>ManuallyDrop<T></code> is subject to the same layout optimizations as <code>T</code>.
As a consequence, it has <em>no effect</em> on the assumptions that the compiler makes
about all values being initialized at their type. In particular, initializing
a <code>ManuallyDrop<&mut T></code> with <a href="fn.zeroed.html"><code>mem::zeroed</code></a> is undefined behavior.</p>
