Implementations

impl VariableDescriptor

pub fn genuine(name: &'static str) -> Self

pub fn chained(name: &'static str) -> Self

Creates a new chained variable descriptor.

Chained variables form chains rooted at anchor problem facts. For example, in vehicle routing: Vehicle ← Customer1 ← Customer2

pub fn list(name: &'static str) -> Self

pub fn shadow(name: &'static str, kind: ShadowVariableKind) -> Self

pub fn with_value_range(self, provider: &'static str) -> Self

pub fn with_allows_unassigned(self, allows: bool) -> Self

pub fn piggyback(name: &'static str, source_shadow: &'static str) -> Self

Creates a piggyback shadow variable descriptor.

Piggyback shadows ride on another shadow variable’s listener, updated as a side-effect without their own dedicated listener.

pub fn with_value_range_type(self, value_range_type: ValueRangeType) -> Self

pub fn with_source(self, entity: &'static str, variable: &'static str) -> Self

pub fn with_usize_accessors( self, getter: UsizeGetter, setter: UsizeSetter, ) -> Self

pub fn with_entity_value_provider( self, provider: UsizeEntityValueProvider, ) -> Self

pub fn with_candidate_values(self, provider: UsizeCandidateValues) -> Self

pub fn with_nearby_value_candidates( self, provider: UsizeCandidateValues, ) -> Self

pub fn with_nearby_entity_candidates( self, provider: UsizeCandidateValues, ) -> Self

pub fn with_nearby_value_distance_meter( self, meter: UsizeNearbyValueDistanceMeter, ) -> Self

pub fn with_nearby_entity_distance_meter( self, meter: UsizeNearbyEntityDistanceMeter, ) -> Self

pub fn with_construction_entity_order_key( self, order_key: UsizeConstructionEntityOrderKey, ) -> Self

pub fn with_construction_value_order_key( self, order_key: UsizeConstructionValueOrderKey, ) -> Self

Trait Implementations

impl Clone for VariableDescriptor

fn clone(&self) -> VariableDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VariableDescriptor

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

Formats the value using the given formatter.
