        <h3>Description</h3>
        <p><span>This function constructs a URL from</span> <span>the string `s`, which must contain a</span>
<span>valid</span>
<i>URI</i>
<span>or</span>
<i>relative-ref</i>
<span>or else an exception is thrown.</span>
<span>The new url retains ownership by</span>
<span>allocating a copy of the passed string.</span></p>

<h3>Example</h3>
<code>
url u( "https://www.example.com" );
</code>
<h3>Effects</h3>
<code>
return url( parse_uri_reference( s ).value() );
</code>
<h3>Postconditions</h3>
<code>
this->buffer().data() != s.data()
</code>
<h3>Complexity</h3>
<p><span>Linear in `s.size()`.</span></p>

<h3>Exception Safety</h3>
<p><span>Calls to allocate may throw.</span>
<span>Exceptions thrown on invalid input.</span></p>

<h3>BNF</h3>
<code>
URI           = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

relative-ref  = relative-part [ "?" query ] [ "#" fragment ]
</code>
<h3>Specification</h3>
