Expand description

Code identifying the reason type. The order here is meaningless. In particular, it gives no indication of whether a given reason will appear before another in the solution, if both apply.

Variants§

§

Unspecified = 0

This should never be used. If we are unable to understand why a shipment was skipped, we simply return an empty set of reasons.

§

NoVehicle = 1

There is no vehicle in the model making all shipments infeasible.

§

DemandExceedsVehicleCapacity = 2

The demand of the shipment exceeds a vehicle’s capacity for some capacity types, one of which is example_exceeded_capacity_type.

§

CannotBePerformedWithinVehicleDistanceLimit = 3

The minimum distance necessary to perform this shipment, i.e. from the vehicle’s start_location to the shipment’s pickup and/or delivery locations and to the vehicle’s end location exceeds the vehicle’s route_distance_limit.

Note that for this computation we use the geodesic distances.

§

CannotBePerformedWithinVehicleDurationLimit = 4

The minimum time necessary to perform this shipment, including travel time, wait time and service time exceeds the vehicle’s route_duration_limit.

Note: travel time is computed in the best-case scenario, namely as geodesic distance x 36 m/s (roughly 130 km/hour).

§

CannotBePerformedWithinVehicleTravelDurationLimit = 5

Same as above but we only compare minimum travel time and the vehicle’s travel_duration_limit.

§

CannotBePerformedWithinVehicleTimeWindows = 6

The vehicle cannot perform this shipment in the best-case scenario (see CANNOT_BE_PERFORMED_WITHIN_VEHICLE_DURATION_LIMIT for time computation) if it starts at its earliest start time: the total time would make the vehicle end after its latest end time.

§

VehicleNotAllowed = 7

The allowed_vehicle_indices field of the shipment is not empty and this vehicle does not belong to it.

Implementations§

source§

impl Code

source

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Code.

source

pub fn from_i32(value: i32) -> Option<Code>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a Code, or None if value is not a valid variant.

source§

impl Code

source

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

source

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.
