pub struct BaseRule { /* private fields */ }

Base implementation for rules with callback support

Implementations

impl BaseRule

pub fn new() -> Self

where F: Fn(&mut RuleContext) -> RuleResult<()> + 'static,

Set the pre-execution function

pub fn set_execute_fn<F>(&mut self, f: F)

where F: Fn(&mut RuleContext) -> RuleResult<()> + 'static,

Set the execution function

pub fn set_post_execute_fn<F>(&mut self, f: F)

where F: Fn(&mut RuleContext) -> RuleResult<()> + 'static,

Trait Implementations

impl Default for BaseRule

fn default() -> Self

Returns the “default value” for a type.

impl Rule for BaseRule

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>>
