        <h3>Description</h3>
        <p><span>This function returns the host portion</span> <span>of the authority as a string, or the</span>
<span>empty string if there is no authority.</span>
<span>Any percent-escapes in the string are</span>
<span>decoded first.</span></p>

<h3>Example</h3>
<code>
assert( url_view( "https://www%2droot.example.com/" ).host() == "www-root.example.com" );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->host().size()`.</span></p>

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

<h3>BNF</h3>
<code>
host        = IP-literal / IPv4address / reg-name

IP-literal  = "[" ( IPv6address / IPvFuture  ) "]"

reg-name    = *( unreserved / pct-encoded / "-" / ".")
</code>
<h3>Specification</h3>
