<p>In general, there may be several ways to "borrow" a piece of data. The
typical ways of borrowing a type <code>T</code> are <code>&T</code> (a shared borrow) and <code>&mut T</code>
(a mutable borrow). But types like <code>Vec<T></code> provide additional kinds of
borrows: the borrowed slices <code>&[T]</code> and <code>&mut [T]</code>.</p>
<p>When writing generic code, it is often desirable to abstract over all ways
of borrowing data from a given type. That is the role of the <code>Borrow</code>
trait: if <code>T: Borrow<U></code>, then <code>&U</code> can be borrowed from <code>&T</code>. A given
type can be borrowed as multiple different types. In particular, <code>Vec<T>: Borrow<Vec<T>></code> and <code>Vec<T>: Borrow<[T]></code>.</p>
<p>If you are implementing <code>Borrow</code> and both <code>Self</code> and <code>Borrowed</code> implement
<code>Hash</code>, <code>Eq</code>, and/or <code>Ord</code>, they must produce the same result.</p>
<p><code>Borrow</code> is very similar to, but different than, <code>AsRef</code>. See
<a href="../../book/first-edition/borrow-and-asref.html">the book</a> for more.</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>)
