Struct RuleRegistry 

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

Interface for querying types of rules. It includes both Discrete and Range value rules. It provides a registry of the various rule types.

Implementations

impl<'a> RuleRegistry<'a>

pub fn get_discrete_value_rule_types(&self) -> Vec<String>

Returns all DiscreteValue rule type IDs.

Returns

A vector of Strings representing rule type IDs that correspond to different DiscreteValues in the RuleRegistry.

pub fn discrete_values_by_type( &self, rule_type_id: String, ) -> Option<Vec<DiscreteValue>>

Returns all DiscreteValues corresponding to the specified rule_type_id.

This methods works in tandem with RuleRegistry::get_discrete_value_rule_types.

Arguments

• rule_type_id - The id of the rule type.

Returns

A vector of DiscreteValues or None if the rule_type_id doesn’t match any type id in the RuleRegistry.

pub fn get_range_rule_types(&self) -> Vec<String>

Returns all Range rule type IDs.

Returns

A vector of Strings representing rule type IDs that correspond to different Ranges in the RuleRegistry.

pub fn range_values_by_type(&self, rule_type_id: String) -> Option<Vec<Range>>

Returns all Ranges corresponding to the specified rule_type_id.

This methods works in tandem with RuleRegistry::get_range_rule_types.

Arguments

• rule_type_id - The id of the rule type.

Returns

A vector of Ranges or None if the rule_type_id doesn’t match any type id in the RuleRegistry.

pub fn get_possible_states_of_rule_type( &self, rule_type_id: String, ) -> Option<RuleValuesByType>

Returns all possible states for a given rule_type_id.

Arguments

• rule_type_id - The id of the rule type.

Returns

An Option containing a RuleValuesByType enum with either a vector of Ranges or a vector of DiscreteValues. Returns None if the rule_type_id is not found.
