Struct PillarSwapMove 

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

A move that swaps values between two pillars.

Stores pillar indices and concrete function pointers for zero-erasure access. do_move returns the previous pillar values as typed undo data.

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, usize) -> Option<V>, setter: fn(&mut S, usize, usize, Option<V>), variable_index: usize, variable_name: &'static str, descriptor_index: usize, ) -> Self

Creates a new pillar swap move with concrete function pointers.

Arguments

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

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

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

Trait Implementations

impl<S, V: Debug> Debug for PillarSwapMove<S, V>

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

Formats the value using the given formatter.

fn for_each_affected_entity<W: FnMut(MoveAffectedEntity<'_>)>( &self, visitor: &mut W, )

A pillar swap mutates BOTH halves. entity_indices() exposes the left pillar as its primary slice, so the trait default would hide every right-pillar entity from pin checks, tabu bookkeeping, and telemetry.
