}

Function-pointer context for list variable solvers.

Carries all domain callbacks and distance meters needed to construct list move selectors without requiring dyn or closures.

Fields

list_len: fn(&S, usize) -> usize

Returns the length of the list for entity i.

list_remove: fn(&mut S, usize, usize) -> Option<V>

Removes element at pos from entity i, returning it (returns None if out of bounds).

list_insert: fn(&mut S, usize, usize, V)

Inserts val at pos in entity i.

list_get: fn(&S, usize, usize) -> Option<V>

Gets element at pos in entity i.

list_set: fn(&mut S, usize, usize, V)

Replaces element at pos in entity i.

list_reverse: fn(&mut S, usize, usize, usize)

Reverses the segment [start, end) in entity i.

sublist_remove: fn(&mut S, usize, usize, usize) -> Vec<V>

Removes segment [start, end) from entity i.

sublist_insert: fn(&mut S, usize, usize, Vec<V>)

Inserts items at pos in entity i.

ruin_remove: fn(&mut S, usize, usize) -> V

Removes element at pos from entity i for ruin moves (panics if out of bounds).

ruin_insert: fn(&mut S, usize, usize, V)

Inserts val at pos in entity i for ruin reinsertion.

entity_count: fn(&S) -> usize

Returns the total number of list owner entities.

cross_distance_meter: DM

Cross-entity (inter-route) distance meter.

intra_distance_meter: IDM

Intra-entity (intra-route) distance meter.

variable_name: &'static str

List variable field name.

descriptor_index: usize

Descriptor index for the list owner entity collection.
