uint16_t rdesc_nonterminal::variant

The production rule variant being parsed.

This field is for the internal use of the rdesc_parser. When the backtracking parser tries different production rules for a non-terminal, it increments this index to track which variant it is currently attempting. This is purely parse-time data.

The documentation for this struct was generated from the following file:
