Struct DiscreteValueRule 

pub struct DiscreteValueRule { /* private fields */ }

Rule

A Rule may have multiple states that affect agent behavior while it is driving through the rule’s zone. The possible states of a Rule must be semantically coherent. The current state of a Rule is given by a [RuleStateProvider]. States can be:

• range based (RangeValueRule).
• discrete (DiscreteValueRule).

DiscreteValueRule

DiscreteValues are defined by a string value. Semantics of this rule are based on all possible values that this DiscreteValueRule::type_id could have (as specified by RuleRegistry::FindRuleByType()), not only the subset of values that a specific instance of this rule can be in.

Implementations

impl DiscreteValueRule

pub fn id(&self) -> String

Returns the Id of the rule as a string.

Returns

The id of the rule.

pub fn type_id(&self) -> String

Returns the type of the rule as a string. Example: “right-of-way-rule-type-id”, “direction-usage-rule-type-id”

Returns

The type id of the rule.

pub fn zone(&self) -> LaneSRoute

Returns a crate::api::LaneSRoute that represents the zone that the rule applies to.

Returns

A crate::api::LaneSRoute representing the zone of the rule.

pub fn states(&self) -> Vec<DiscreteValue>

Returns the states of the rule.

Returns

A vector of DiscreteValues representing the states of the rule. If the rule has no states, an empty vector is returned.

Trait Implementations

impl Debug for DiscreteValueRule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
