Trait ScoringFeatureSource 

pub trait ScoringFeatureSource {
    // Required methods
    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>;

    // Provided method
    fn returned_value(&self, _column: &str) -> Option<&Value> { ... }
}

Feature values the engine can supply for one candidate.

Required Methods

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>

Provided Methods

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
