}

Core trait for rule execution with proper error handling

Required Methods

fn evaluate(&self, context: &RuleContext) -> RuleResult<bool>

Evaluate if this rule should execute

fn execute(&mut self, context: &mut RuleContext) -> RuleResult<()>

Execute the rule with proper error handling

fn children(&self) -> &[Box<dyn Rule>]

Get immutable reference to children

fn children_mut(&mut self) -> &mut Vec<Box<dyn Rule>>

Get mutable reference to children

fn add_child(&mut self, child: Box<dyn Rule>) -> RuleResult<()>

Add a child rule

Provided Methods

fn add_children(&mut self, children: Vec<Box<dyn Rule>>) -> RuleResult<()>

Add multiple child rules

fn fire(&mut self, context: &mut RuleContext) -> RuleResult<bool>

Execute the complete rule lifecycle: evaluate, execute, and run children
