Struct PillarSwapMove 

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

A move that swaps values between two pillars.

Stores pillar 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> PillarSwapMove<S, V>

pub fn new( left_indices: Vec<usize>, right_indices: Vec<usize>, 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 swap move with typed function pointers.

Arguments

• left_indices - Indices of entities in the left pillar
• right_indices - Indices of entities in the right pillar
• getter - Typed getter function pointer
• setter - Typed setter function pointer
• variable_name - Name of the variable being swapped
• descriptor_index - Index in the entity descriptor

pub fn left_indices(&self) -> &[usize]

Returns the left pillar indices.

pub fn right_indices(&self) -> &[usize]

Returns the right pillar indices.
