Struct DiscreteValueRuleStateProvider 

pub struct DiscreteValueRuleStateProvider<'a> { /* private fields */ }

Provides the dynamic state of DiscreteValueRules.

While a RoadRulebook provides the static definitions of rules, a DiscreteValueRuleStateProvider provides the current state of those rules at runtime. This allows for querying what state a rule is currently in, which is essential for dynamic systems where rule states can change over time (e.g., traffic light phases changing).

Implementations

impl<'a> DiscreteValueRuleStateProvider<'a>

pub fn get_state_by_rule_id( &self, rule_id: &String, ) -> Option<StateProviderQuery<DiscreteValue>>

Gets a state from the provider based on it’s rule_id.

Arguments

• rule_id - A Rule ID.

Returns

An Option containing the StateProviderQuery with a DiscreteValue if the rule_id matches with any rule. Otherwise, None is returned.

pub fn get_state_by_rule_type( &self, road_position: &RoadPosition, rule_type: RuleType, tolerance: f64, ) -> Option<StateProviderQuery<DiscreteValue>>

Gets a state from the provider if there is a rule_type in the received road_position.

Arguments

• road_position - A position in the road geometry.
• rule_type - A Rule Type.
• tolerance - The tolerance in which to look for the Rule of type rule_type around the road_position.

Returns

An Option containing the StateProviderQuery with a DiscreteValue if rule_type matches with any rule’s type near road_position. Otherwise, None is returned.
