Struct TemporalScorer 

pub struct TemporalScorer { /* private fields */ }

Temporal decay scorer

Implementations

impl TemporalScorer

pub fn new(config: TemporalDecayConfig) -> Self

Create a new temporal scorer with current time as reference

pub fn with_reference_time( config: TemporalDecayConfig, reference_time: f64, ) -> Self

Create with specific reference time

pub fn default_scorer() -> Self

Create with default config

pub fn decay_score(&self, timestamp_secs: f64) -> f32

Calculate decay score for a given timestamp

Returns a value between min_decay and 1.0

pub fn decay_score_duration(&self, age: Duration) -> f32

Calculate decay score from Duration

pub fn blend_scores(&self, semantic_score: f32, decay_score: f32) -> f32

Blend semantic and decay scores

final = α × semantic + (1-α) × decay

pub fn final_score(&self, semantic_score: f32, timestamp_secs: f64) -> f32

Calculate final score from semantic score and timestamp

pub fn apply_decay<I>(&self, results: I) -> Vec<(String, f32)>

where I: IntoIterator<Item = (String, f32, f64)>,

Apply temporal decay to a list of scored results

Each result is (id, semantic_score, timestamp) Returns (id, final_score) sorted by final_score descending

pub fn apply_decay_typed<T, F>( &self, results: &mut [T], get_score: impl Fn(&T) -> f32, get_timestamp: impl Fn(&T) -> f64, set_score: F, )

where F: Fn(&mut T, f32),

Apply decay to typed results

pub fn half_life_display(&self) -> String

Get the half-life in human-readable format
