<p>Some types make it possible to go from borrowed to owned, usually by
implementing the <code>Clone</code> trait. But <code>Clone</code> works only for going from <code>&T</code>
to <code>T</code>. The <code>ToOwned</code> trait generalizes <code>Clone</code> to construct owned data
from any borrow of a given type.</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>)
