Struct vrp_core::construction::constraints::AreaModule

pub struct AreaModule { /* fields omitted */ }

An area module provides way to restrict given actor to work in specific areas only.

Implementations

impl AreaModule

pub fn new(
    area_resolver: AreaResolver,
    location_resolver: LocationResolver,
    code: i32
) -> Self

Creates a new instance of AreaModule.

Trait Implementations

impl ConstraintModule for AreaModule

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.

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

Accept route and updates its state to allow more efficient constraint checks.

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.
