Set the host to an address.

url_base&
set_host_ipvfuture(
    string_view s);

The host is set to the specified IPvFuture string. The host type will be host_type::ipvfuture.

assert( url().set_host_ipvfuture( "v42.bis" ).buffer() == "//[v42.bis]" );

Linear in this->size() + s.size().

this->has_authority() == true && this->host_ipvfuture) == s && this->host_type() == host_type::ipvfuture
