Struct vrp_core::construction::constraints::ConditionalJobModule

pub struct ConditionalJobModule { /* fields omitted */ }

A module which allows to promote jobs between required and ignored collection using some condition. Useful to model some optional/conditional activities, e.g. breaks, refueling, etc.

Implementations

impl ConditionalJobModule

pub fn new(
    context_transition: Box<dyn JobContextTransition + Send + Sync>
) -> Self

Creates a new instance of ConditionalJobModule.

Trait Implementations

impl ConstraintModule for ConditionalJobModule

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.
