Struct vrp_core::construction::constraints::StrictLockingModule

pub struct StrictLockingModule { /* fields omitted */ }

A module which allows to lock specific actors within specific jobs using different rules.

Implementations

impl StrictLockingModule

pub fn new(fleet: &Fleet, locks: &[Arc<Lock>], code: i32) -> Self

Creates an instance of StrictLockingModule.

Trait Implementations

impl ConstraintModule for StrictLockingModule

fn accept_insertion(
    &self,
    _solution_ctx: &mut SolutionContext,
    _route_index: usize,
    _job: &Job
)

Accept insertion of specific job into the route. Called once job has been inserted into solution represented via solution_ctx. Target route is defined by route_index which refers to routes collection in solution context. Inserted job is job. This method should call accept_route_state internally. This method should NOT modify amount of job activities in the tour.

fn accept_route_state(&self, _ctx: &mut RouteContext)

Accept route and updates its state to allow more efficient constraint checks. This method should NOT modify amount of job activities in the tour.

fn accept_solution_state(&self, _ctx: &mut SolutionContext)

Accepts insertion solution context allowing to update job insertion data. This method called twice: before insertion of all jobs starts and when it ends. Please note, that it is important to update only stale routes as this allows to avoid updating non changed route states.

fn state_keys(&self) -> Iter<'_, i32>

Returns unique constraint state keys. Used to avoid state key interference.

fn get_constraints(&self) -> Iter<'_, ConstraintVariant>

Returns list of constraints to be used.
