Struct ScoringEngine 

pub struct ScoringEngine { /* private fields */ }

Engine that defines scoring axes and computes multi-axis scores.

Implementations

impl ScoringEngine

pub fn new() -> Self

Create an empty scoring engine with no axes defined.

pub fn define_axes(&mut self, axes: Vec<(&str, f64)>)

Define the scoring axes and their weights.

Replaces any previously defined axes.

pub fn score( &self, entity_id: &str, values: &HashMap<String, f64>, ) -> ContinuousScore

Score an entity by providing values for each defined axis.

Values not present in values default to 0.0. The composite score is the weighted average of all axes. Confidence is the fraction of defined axes that had values provided.

pub fn rank(scores: &mut [ContinuousScore])

Sort a slice of scores by composite score in descending order.

pub fn get_outliers( scores: &[ContinuousScore], threshold: f64, ) -> Vec<&ContinuousScore>

Return scores whose composite value deviates from the mean by more than threshold (in absolute terms).

Trait Implementations

impl Serialize for ScoringEngine

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
