Struct vrp_core::construction::constraints::ConcreteJobContextTransition

pub struct ConcreteJobContextTransition<FRemoveRequired, FPromoteRequired, FRemoveLocked, FPromoteLocked> where
    FRemoveRequired: Fn(&SolutionContext, &Job) -> bool,
    FPromoteRequired: Fn(&SolutionContext, &Job) -> bool,
    FRemoveLocked: Fn(&SolutionContext, &Job) -> bool,
    FPromoteLocked: Fn(&SolutionContext, &Job) -> bool,  {
    pub remove_required: FRemoveRequired,
    pub promote_required: FPromoteRequired,
    pub remove_locked: FRemoveLocked,
    pub promote_locked: FPromoteLocked,
}

A concrete implementation of JobContextTransition which allows to use lambdas.

Fields

remove_required: FRemoveRequired

A function which removes job from required list.

promote_required: FPromoteRequired

A function which promotes job to required jobs.

remove_locked: FRemoveLocked

A function which removes job from locked list.

promote_locked: FPromoteLocked

A function which promotes job to locked jobs.
