Struct FeatureMissingnessTracker 

pub struct FeatureMissingnessTracker {
    pub feature_id: String,
    pub consecutive_missing: usize,
    pub total_missing: usize,
    pub invalidation_events: Vec<usize>,
}

Per-feature missingness tracker.

Accumulates consecutive missing runs and emits DriftValidity::Unknown once the threshold is exceeded.

Fields

feature_id: String

Feature identifier.

consecutive_missing: usize

Current consecutive missing run count.

total_missing: usize

Total missing runs across the entire run sequence.

invalidation_events: Vec<usize>

Run indices where missingness triggered drift invalidation.

Implementations

impl FeatureMissingnessTracker

pub fn new(feature_id: impl Into<String>) -> Self

pub fn update(&mut self, is_missing: bool, run_index: usize) -> DriftValidity

Update the tracker for a single run.

• is_missing — whether the sensor value for this run is absent.
• run_index — zero-based run counter (used in invalidation events).

Returns the DriftValidity for this run.

pub fn is_invalidated(&self) -> bool

Returns true if drift is currently invalidated.
