        <pre class="source-code cpp">
            template<class StringToken = string_token::return_string>

        <h3>Description</h3>
        <p><span>If present, this function returns a</span> <span>string representing the userinfo (which</span>
<span>may be empty).</span>
<span>Otherwise it returns an empty string.</span>
<span>Any percent-escapes in the string are</span>
<span>decoded first.</span></p>

<div>
<h4>NOTE</h4>
<p><span>This function uses the string token</span>
<span>return type customization. Depending on</span>
<span>the token passed, the return type and</span>
<span>behavior of the function can be different.</span>
<span>See</span>
<span>string_token::return_string</span>
<span>for more information.</span></p>

</div>
<h3>Example</h3>
<code>
assert( url_view( "http://jane%2Ddoe:pass@example.com" ).userinfo() == "jane-doe:pass" );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->userinfo().size()`.</span></p>

<h3>Exception Safety</h3>
<p><span>Calls to allocate may throw.</span></p>

<h3>BNF</h3>
<code>
userinfo    = user [ ":" [ password ] ]

authority   = [ userinfo "@" ] host [ ":" port ]
