Struct BindingScoreFeatures 

pub struct BindingScoreFeatures<'a> { /* private fields */ }

Reads scoring features from one row.

The legacy source reads the declared score column and returned value aliases. The opt-in retriever source reads engine-owned original score/observed hop annotations and properties of its canonical pinned candidate node. Graph-seed relevance is supplied only by the declared canonical graph-seed producer.

Trait Implementations

impl ScoringFeatureSource for BindingScoreFeatures<'_>

fn returned_value(&self, column: &str) -> Option<&Value>

Borrowed, explicitly returned metadata for a host’s cohort policy, such as an exact reason/tie key. It does not establish retrieval provenance.

fn search_score(&self) -> Option<f64>

fn graph_seed_score(&self) -> Option<f64>

fn hop_distance(&self) -> Option<usize>

fn numeric_property(&self, property: &str) -> Option<f64>

fn timestamp_millis(&self, property: &str) -> Option<u64>
