Properties

audioSamplesPlayed ↔ Int64
getter/setter pair
createdAtNs ↔ Int64
Monotonic producer-side timestamp in nanoseconds. Set by the producer (C++ dispatcher) at event-emit time; read by consumers (5-SDK perf_bench + p50 benchmark CI) to compute event-to-frontend latency without relying on wall-clock sync. Encoded as int64 so std::chrono::steady_clock::now().time_since_epoch() values fit directly (2^63 ns ≈ 292 years of runtime headroom).
getter/setter pair
endToEndMs ↔ double
getter/setter pair
hashCode → int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setter
isFrozen → bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
isOverBudget ↔ bool
True when end_to_end_ms exceeded the PipelineOptions.latency_budget_ms configured for this run. Frontends can surface this to the UI for SLO dashboards without re-computing the threshold themselves.

llmFirstTokenMs ↔ double
getter/setter pair
llmTotalMs ↔ double
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
