reference value within generic code.</p>
<p><code>AsRef</code> is very similar to, but serves a slightly different purpose than,
<a href="../../std/borrow/trait.Borrow.html"><code>Borrow</code></a>.</p>
<p><code>AsRef</code> is to be used when wishing to convert to a reference of another
type.
<code>Borrow</code> is more related to the notion of taking the reference. It is
useful when wishing to abstract over the type of reference
(<code>&T</code>, <code>&mut T</code>) or allow both the referenced and owned type to be treated
in the same manner.</p>
<p>The key difference between the two traits is the intention:</p>
<ul>
<li>Use <code>AsRef</code> when goal is to simply convert into a reference</li>
<li>Use <code>Borrow</code> when goal is related to writing code that is agnostic to the
type of borrow and if is reference or value</li>
</ul>
<p>See <a href="../../book/first-edition/borrow-and-asref.html">the book</a> for a more detailed comparison.</p>
<p><strong>Note: this trait must not fail</strong>. If the conversion can fail, use a
dedicated method which returns an <a href="../../std/option/enum.Option.html"><code>Option<T></code></a> or a <a href="../../std/result/enum.Result.html"><code>Result<T, E></code></a>.</p>
<h1 id="generic-implementations" class="section-header"><a href="#generic-implementations">Generic Implementations</a></h1>
<ul>
<li><code>AsRef</code> auto-dereferences if the inner type is a reference or a mutable
reference (e.g.: <code>foo.as_ref()</code> will work the same if <code>foo</code> has type
<code>&mut Foo</code> or <code>&&mut Foo</code>)</li>
</ul>
<h1 id="examples" class="section-header"><a href="#examples">Examples</a></h1>
<p>Both <a href="../../std/string/struct.String.html"><code>String</code></a> and <code>&str</code> implement <code>AsRef<str></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>)
