Function parse_policy_rule 

fn parse_policy_rule(
    config: PolicyRuleConfig,
) -> Result<PolicyRule, ConfigError>

Converts a deserialized PolicyRuleConfig into a validated PolicyRule.

Returns an error if the rule’s trigger or any contained action is invalid.

Examples

let cfg = PolicyRuleConfig {
    trigger: "task_end".to_string(),
    actions: vec![ActionConfig::Summarize { target: "log".to_string() }],
};
let rule = parse_policy_rule(cfg).expect("valid policy rule");
assert_eq!(rule.trigger.to_string(), "task_end");
assert_eq!(rule.actions.len(), 1);
