Struct vrp_core::construction::constraints::CapacityConstraintModule

pub struct CapacityConstraintModule<T: Load + Add<Output = T> + Sub<Output = T> + 'static> { /* fields omitted */ }

A module which ensures vehicle capacity limitation while serving customer's demand.

Implementations

impl<T: Load + Add<Output = T> + Sub<Output = T> + 'static> CapacityConstraintModule<T>

pub fn new(code: i32) -> Self

Creates a new instance of CapacityConstraintModule without multi trip (reload) functionality

pub fn new_with_multi_trip(
    code: i32,
    multi_trip: Arc<dyn MultiTrip<T> + Send + Sync>
) -> Self

Creates a new instance of CapacityConstraintModule with multi trip (reload) functionality

Trait Implementations

impl<T: Load + Add<Output = T> + Sub<Output = T> + 'static> ConstraintModule for CapacityConstraintModule<T>

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.

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.
