Module dispatch 

Pluggable dispatch strategies (SCAN, LOOK, nearest-car, ETD). Pluggable dispatch strategies for assigning elevators to stops.

Example: custom dispatch strategy

use elevator_core::prelude::*;
use elevator_core::dispatch::{
    DispatchDecision, DispatchManifest, ElevatorGroup,
};

struct AlwaysFirstStop;

impl DispatchStrategy for AlwaysFirstStop {
    fn decide(
        &mut self,
        _elevator: EntityId,
        _elevator_position: f64,
        group: &ElevatorGroup,
        _manifest: &DispatchManifest,
        _world: &elevator_core::world::World,
    ) -> DispatchDecision {
        group.stop_entities().first()
            .map(|&stop| DispatchDecision::GoToStop(stop))
            .unwrap_or(DispatchDecision::Idle)
    }
}

let sim = SimulationBuilder::demo()
    .dispatch(AlwaysFirstStop)
    .build()
    .unwrap();

scan

SCAN dispatch algorithm. SCAN (elevator) dispatch algorithm — sweeps end-to-end before reversing.

Structs

DispatchManifest

Full demand picture for dispatch decisions.

ElevatorGroup

Runtime elevator group: a set of lines sharing a dispatch strategy.

LineInfo

Per-line relationship data within an ElevatorGroup.

RiderInfo

Metadata about a single rider, available to dispatch strategies.

Enums
