Struct AccuracyTracker 

pub struct AccuracyTracker { /* private fields */ }

Accuracy tracker that monitors multiple models.

Thread-safe — models wrapped in RwLock.

Implementations

impl AccuracyTracker

pub fn new(config: AccuracyTrackerConfig) -> Self

Creates a new accuracy tracker with the given configuration.

pub fn register_model( &self, measurement: &str, model_name: &str, created_at_epoch_secs: i64, )

Register a model for tracking.

pub fn add_observation( &self, measurement: &str, model_name: &str, actual: f64, predicted: f64, )

Add an observation (actual vs predicted) for a tracked model.

pub fn metrics( &self, measurement: &str, model_name: &str, ) -> Option<VersionAccuracy>

Get current accuracy metrics for a model.

pub fn needs_refit(&self, measurement: &str, model_name: &str) -> bool

Check if a model needs re-fitting based on sustained accuracy degradation.

pub fn is_stale( &self, measurement: &str, model_name: &str, now_epoch_secs: i64, ) -> bool

Check if a model is stale (older than max_model_age_secs).

pub fn model_age_secs( &self, measurement: &str, model_name: &str, now_epoch_secs: i64, ) -> Option<i64>

Get model age in seconds.

pub fn tracked_model_count(&self) -> usize

Number of tracked models.
