How to access parse_state from dsl::scan or lexy::rule_scanner?

[Korsar13]

struct known_user_type: lexy::scan_production<std::string>
{
	template <typename Reader, typename Context>
	static constexpr scan_result scan( lexy::rule_scanner<Context, Reader>& scanner )
	{
		// scanner.context() -- private method?
	}
};

You don't want to access the context directly, it is an implementation detail. Actual parse state can be accessed in a second parameter. an example is here: https://github.com/foonathan/clauf/blob/25b91226c1e8193c4498149cbedf69c2068458da/src/compiler.cpp#L1458
