Struct PillarChangeMove 

pub struct PillarChangeMove<S, V> { /* private fields */ }

A move that assigns a value to all entities in a pillar.

Stores entity indices and typed function pointers for zero-erasure access. Undo is handled by RecordingScoreDirector, not by this move.

Type Parameters

• S - The planning solution type
• V - The variable value type

Implementations

impl<S, V> PillarChangeMove<S, V>

pub fn new( entity_indices: Vec<usize>, to_value: Option<V>, getter: fn(&S, usize) -> Option<V>, setter: fn(&mut S, usize, Option<V>), variable_name: &'static str, descriptor_index: usize, ) -> Self

Creates a new pillar change move with typed function pointers.

Arguments

• entity_indices - Indices of entities in the pillar
• to_value - The new value to assign to all entities
• getter - Typed getter function pointer
• setter - Typed setter function pointer
• variable_name - Name of the variable being changed
• descriptor_index - Index in the entity descriptor

pub fn pillar_size(&self) -> usize

Returns the pillar size.

pub fn to_value(&self) -> Option<&V>

Returns the target value.
