How to use the xiblint.rules.rule_checkers.items function in xiblint

def __init__(self, config, default_rules_config, data):
        self.config = config
        self.path_rules = data.get('rules')
        validate_rule_patterns(self.path_rules)
        self.excluded_rules = data.get('excluded_rules', [])
        validate_rule_patterns(self.excluded_rules)
        self._rules_config = (data.get('rules_config', {}) or
                              default_rules_config)

        # Filter checkers
        patterns = self.path_rules if self.path_rules is not None else self.config.rules
        excluded_patterns = self.excluded_rules
        self.checkers = {
            rule: klass for (rule, klass) in xiblint.rules.rule_checkers.items()
            if any(fnmatch(rule, pattern) for pattern in patterns) and
            not any(fnmatch(rule, pattern) for pattern in excluded_patterns)
        }
