Expand description

Pluggable strategy for repositioning idle elevators.

After the dispatch phase, elevators that remain idle (no pending assignments) are candidates for repositioning. The strategy decides where each idle elevator should move to improve coverage and reduce expected response times.

Implementations receive the set of idle elevator positions and the group’s stop positions, then return a target stop for each elevator (or None to leave it in place).

Required Methods§

Source

fn reposition( &mut self, idle_elevators: &[(EntityId, f64)], stop_positions: &[(EntityId, f64)], group: &ElevatorGroup, world: &World, out: &mut Vec<(EntityId, EntityId)>, )

Decide where to reposition idle elevators.

Push (elevator_entity, target_stop_entity) pairs into out. The buffer is cleared before each call — implementations should only push, never read prior contents. Elevators not pushed remain idle.
