<p>Any sequence of <code>%</code> followed by two hexadecimal digits is decoded.
|

The return type:</p>
|

<ul>
|
||
<li>Implements <code>Into<Cow<u8>></code> borrowing <code>input</code> when it contains no percent-encoded sequence,</li>
|
||
<li>Implements <code>Iterator<Item = u8></code> and therefore has a <code>.collect::<Vec<u8>>()</code> method,</li>
|

<li>Has <code>decode_utf8()</code> and <code>decode_utf8_lossy()</code> methods.</li>
