[Qi] Phrase parsed but iterator did not reach end

Hello,

Or the iterator backtracked?

Is it possible for a phrase to parse (returns true), but the iterator
does not reach the end, or was backtracked?

Depending on the rule, of course. For which I currently have:

boost::spirit::qi::rule<Iterator> _port_rule;

_port_rule = digit
    | (char_('1', '5') >> repeat(1, 4)[digit])
    | (char_('7', '9') >> repeat(1, 3)[digit])
    | (char_('6')
        >> ((char_('0', '4') >> repeat(0, 3)[digit])
            | (char_('6', '9') >> repeat(0, 2)[digit])
            | (char_('5')
                >> ((char_('0', '4') >> repeat(0, 2)[digit])
                    | (char_('6', '9') >> -digit)
                    | (char_('5')
                        >> ((char_('0', '2') >> -digit)
                            | char_('4', '9')
                            | (char_('3') >> char_('0', '5'))
                            )
                        )
                    )
                )
            )
        )
    ;

Where Iterator is a Struct Template argument.

Basically to validate all the patterns from 0-65535 (valid port range).
