middle slice the greatest length possible for a given type and input slice, but only
your algorithm's performance should depend on that, not its correctness.</p>
<p>This method has no purpose when either input element <code>T</code> or output element <code>U</code> are
zero-sized and will return the original slice without splitting anything.</p>
<h1 id="unsafety" class="section-header"><a href="#unsafety">Unsafety</a></h1>
<p>This method is essentially a <code>transmute</code> with respect to the elements in the returned
middle slice, so all the usual caveats pertaining to <code>transmute::<T, U></code> also apply here.</p>
