Struct ReferenceDivergenceRecorder 

pub struct ReferenceDivergenceRecorder { /* private fields */ }

Hold a single Counter instrument so a recipe wiring repeated cross-checks doesn’t pay for a fresh u64_counter build per divergence. Internally cached; cloning is cheap (the counter is reference-counted in OTEL).

Implementations

impl ReferenceDivergenceRecorder

pub fn new(meter: Meter) -> Self

Build bound to the given meter. Counter is built lazily on first record.

pub fn record( &self, stage: &str, kind: SubMsStageKind, reference_kind: &str, expected: &str, observed: &str, )

Record a divergence event. Stage + kind identify the bench surface, reference_kind names the reference algorithm class, expected + observed are stringified scalar deltas.
