Struct Code

pub struct Code(/* private fields */);

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.

Implementations

impl Code

pub const CODE_UNSPECIFIED: Code

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

pub const NO_VEHICLE: Code

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

pub const DEMAND_EXCEEDS_VEHICLE_CAPACITY: Code

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

pub const CANNOT_BE_PERFORMED_WITHIN_VEHICLE_DISTANCE_LIMIT: Code

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.

pub const CANNOT_BE_PERFORMED_WITHIN_VEHICLE_DURATION_LIMIT: Code

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).

pub const CANNOT_BE_PERFORMED_WITHIN_VEHICLE_TRAVEL_DURATION_LIMIT: Code

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

pub const CANNOT_BE_PERFORMED_WITHIN_VEHICLE_TIME_WINDOWS: Code

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.

pub const VEHICLE_NOT_ALLOWED: Code

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

pub fn value(&self) -> i32

Gets the enum value.

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

Gets the enum value as a string.

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

Creates an enum value from the value name.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Code

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Code

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Code

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<i32> for Code

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Code

fn eq(&self, other: &Code) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Code

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Code
