Struct ScoringProgram 

pub struct ScoringProgram { /* private fields */ }

Validated reusable scoring template with coefficients supplied by the host.

Unlike the legacy sum-only ScoringSpec, a program explicitly declares both composition and missing-signal behavior. Time is an execution input, never captured while constructing or caching a program.

Implementations

impl ScoringProgram

pub fn new( combination: ScoringCombination, missing: MissingScoringFeature, spec: ScoringSpec, ) -> Result<Self, ScoringProgramError>

pub fn specification(&self) -> &ScoringSpec

pub fn shape(&self) -> ScoringProgramShape

pub fn neutral_template(&self) -> Self

A cache template retains no previous request’s coefficients.

pub fn evaluate_score( &self, source: &impl ScoringFeatureSource, reference_time_millis: u64, ) -> Result<f64, ScoringProgramError>

pub fn evaluate( &self, source: &impl ScoringFeatureSource, reference_time_millis: u64, ) -> Result<ScoringEvaluation, ScoringProgramError>
