Struct SealedRuntimeObservationSnapshot 

pub struct SealedRuntimeObservationSnapshot { /* private fields */ }

Immutable sealed snapshot accepted by the JSONL exporter.

Implementations

impl SealedRuntimeObservationSnapshot

pub fn manifest(&self) -> &RuntimeObservationManifest

Immutable session manifest.

pub fn topology(&self) -> impl ExactSizeIterator<Item = &RuntimeTopologyRecord>

Static topology sorted by typed row identity.

pub fn events(&self) -> &[RuntimeTimelineEvent]

Dynamic events sorted by recorder sequence.

pub fn footer(&self) -> &RuntimeObservationFooter

Completeness, terminal, loss, and degradation metadata.

pub fn attempt_report(&self) -> Option<&QueryAttemptReport>

Fixed execution-attempt summary, when this observation belongs to an attempt.

The embedded report is the same immutable value delivered by the attempt completion. In particular, report_ready_ns is fixed before this snapshot is published and the JSONL footer serializes this exact allocation.

impl SealedRuntimeObservationSnapshot

pub fn query_metrics(&self, plan: &PlanExecutionId) -> Option<&QueryMetrics>

The metrics of plan execution plan, as frozen when its owner projected them or, failing that, when this session sealed. None means that the snapshot has no frozen metrics for that invocation.
