Enum google_api_proto::google::cloud::optimization::v1::injected_solution_constraint::constraint_relaxation::relaxation::Level

#[repr(i32)]
pub enum Level {
    Unspecified = 0,
    RelaxVisitTimesAfterThreshold = 1,
    RelaxVisitTimesAndSequenceAfterThreshold = 2,
    RelaxAllAfterThreshold = 3,
}

Expresses the different constraint relaxation levels, which are applied for a visit and those that follow when it satisfies the threshold conditions.

The enumeration below is in order of increasing relaxation.

Variants

Unspecified = 0

Implicit default relaxation level: no constraints are relaxed, i.e., all visits are fully constrained.

This value must not be explicitly used in level.

RelaxVisitTimesAfterThreshold = 1

Visit start times and vehicle start/end times will be relaxed, but each visit remains bound to the same vehicle and the visit sequence must be observed: no visit can be inserted between them or before them.

RelaxVisitTimesAndSequenceAfterThreshold = 2

Same as RELAX_VISIT_TIMES_AFTER_THRESHOLD, but the visit sequence is also relaxed: visits can only be performed by this vehicle, but can potentially become unperformed.

RelaxAllAfterThreshold = 3

Same as RELAX_VISIT_TIMES_AND_SEQUENCE_AFTER_THRESHOLD, but the vehicle is also relaxed: visits are completely free at or after the threshold time and can potentially become unperformed.

Implementations

impl Level

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Level.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl Level

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.

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

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

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Default for Level

fn default() -> Level

Returns the “default value” for a type.

impl From<Level> for i32

fn from(value: Level) -> i32

Converts to this type from the input type.

impl Hash for Level

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Level

fn cmp(&self, other: &Level) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Level

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Level

fn partial_cmp(&self, other: &Level) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for Level

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Level, DecodeError>

Performs the conversion.

impl Copy for Level

impl Eq for Level

impl StructuralPartialEq for Level
