Struct Classifier 

pub struct Classifier { /* private fields */ }

Incremental classifier. Feed events in, snapshot out.

Implementations

impl Classifier

pub fn new() -> Self

pub fn push(&mut self, event: Event)

Append an event. Events must be monotonically non-decreasing in ts; the classifier does not re-sort.

pub fn classify(&self, now: DateTime<Utc>) -> Snapshot

Compute a fresh snapshot as of now.

Uses Snapshot::new, which caps friction at L2. Callers with engine context (the dispatcher, the TUI’s operator- state refresh path) should use Self::classify_with_risk to reach L3/L4.

pub fn classify_with_risk( &self, now: DateTime<Utc>, risk: RiskContext, ) -> Snapshot

Compute a fresh snapshot as of now, folding engine-reported risk context into the friction level.

The event-pure part of the classifier is unchanged — risk participates only at the final Snapshot construction via Snapshot::new_with_risk. Passing RiskContext::default is equivalent to calling Self::classify.

This entrypoint is what the TUI calls on every tick once the engine mirror has a live Risk payload; the additional O(1) work is a pair of integer comparisons and a branch, so the p95 budget from classifier_tick_under_budget_on_typical_load is unaffected.

pub fn event_count(&self) -> usize

Total events consumed.

Trait Implementations
