Enum Objective 

pub enum Objective {
    Max,
    Min,
}

Whether a criterion / objective is to be maximised or minimised. Used by pareto (dominance direction) and, via wsm::Direction, by the WSM scorer.

Variants

Max

Larger is better (coverage, availability, utility …).

Min

Smaller is better (cost, mass, PDOP, revisit gap …).

Implementations

impl Objective

pub fn min_sign(self) -> f64

The sign that turns this objective into a minimisation of sign * value (so a single code path can treat every objective as “smaller is better”).

Trait Implementations

impl Clone for Objective

fn clone(&self) -> Objective

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Objective

impl Debug for Objective

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Objective

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Objective

impl From<Direction> for Objective

fn from(d: Direction) -> Self

Converts to this type from the input type.

impl PartialEq for Objective

fn eq(&self, other: &Objective) -> 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 Objective

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
