Could you please elaborate on how exactly your question is connected to parsing? What are you trying to achieve with your example? Parse integers? |

You can use
maximum_rule< std::uint8_t >, as seen intao/pegtl/contrib/uri.hpp. The maximum_rule allows you to specify the datatype into which a parsed number must fit, as well as an optional maximum value. You could usemaximum_rule< std::uint8_t, 123 >as a rule that parses/matches any number from 0 to 123.
