Struct MissingnessAwareGrammar 

pub struct MissingnessAwareGrammar { /* private fields */ }

Applies the missingness policy across all features in a run sequence.

Call MissingnessAwareGrammar::process once per feature with the raw imputed-value vector and the corresponding is_imputed mask.

The returned MissingnessAwareRecord vector can be used to gate the downstream grammar layer: any record with suppressed_by_missingness = true should be held at the previous grammar state rather than allowing a new transition.

Implementations

impl MissingnessAwareGrammar

pub fn new() -> Self

pub fn process( &mut self, feature_id: &str, values: &[f64], is_imputed: &[bool], ) -> Vec<MissingnessAwareRecord>

Process a feature’s run sequence and return annotated records.

Arguments

• feature_id — sensor identifier.
• values — slice of imputed sensor values (one per run).
• is_imputed — parallel slice indicating which values were imputed (i.e., the original sensor reading was missing).

pub fn trackers(&self) -> &HashMap<String, FeatureMissingnessTracker>

Return all feature trackers for serialisation into the traceability manifest.

pub fn summary(&self) -> MissingSummary

Return a summary for embedding in the run manifest JSON.
