Struct CorpusQuality 

pub struct CorpusQuality { /* private fields */ }

Composite metric: a single tuner-friendly score that fuses EVR, bridge coherence, curvature health, and category balance.

Construct via CorpusQuality::new or CorpusQuality::default. The most recent sub-score breakdown is cached in a Mutex (the QualityMetric trait requires Send + Sync) and is readable via Self::last_breakdown after each call to Self::score.

Implementations

impl CorpusQuality

pub fn new(weights: CorpusQualityWeights) -> Self

Construct with explicit weights. Panics if weights are invalid (non-finite, negative, or all zero) — invalid weights are a programmer error, not a runtime condition the tuner should silently mask.

pub fn weights(&self) -> CorpusQualityWeights

pub fn last_breakdown(&self) -> Option<CorpusQualityBreakdown>

Snapshot of the sub-scores from the most recent score() call. Returns None before the first call.

Trait Implementations

impl Clone for CorpusQuality

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CorpusQuality

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

Formats the value using the given formatter.

impl Default for CorpusQuality

fn default() -> Self

Returns the “default value” for a type.

impl QualityMetric for CorpusQuality

fn name(&self) -> &str

Short identifier for logs and tuner reports.

fn score(&self, pipeline: &SphereQLPipeline) -> f64

Evaluate the pipeline. Must return a value in [0, 1].

fn score_with_components( &self, pipeline: &SphereQLPipeline, ) -> (f64, Vec<(String, f64, f64)>)

Evaluate the pipeline and report any per-component breakdown in the same pass. Returns (score, components) where each component is (name, weight, component_score).
