        <h3>Synopsis</h3>
        <div>
            <code>

        <h3>Description</h3>
        <p><span>The host is set to the specified IPvFuture</span> <span>string.</span> <span>The host type is</span>
<span>host_type::ipvfuture</span>
<span>.</span></p>

<h3>Example</h3>
<code>
assert( url().set_host_ipvfuture( "v42.bis" ).buffer() == "//[v42.bis]" );
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->size() + s.size()`.</span></p>

<h3>Postconditions</h3>
<code>
this->has_authority() == true && this->host_ipvfuture) == s && this->host_type() == host_type::ipvfuture
</code>
<h3>Exception Safety</h3>
<p><span>Strong guarantee.</span>
<span>Calls to allocate may throw.</span>
<span>Exceptions thrown on invalid input.</span></p>

<h3>BNF</h3>
<code>
IPvFuture     = "v" 1*HEXDIG "." 1*( unreserved / sub-delims / ":" )
</code>
