Struct TimerObservabilitySnapshot 

pub struct TimerObservabilitySnapshot { /* private fields */ }

Epoch-scoped outcomes, counters, and performance for one timer.

Implementations

impl TimerObservabilitySnapshot

pub fn new(epoch: TimerEpoch) -> Self

Begin empty observation state for one runtime epoch.

pub fn begin_epoch(&mut self, epoch: TimerEpoch)

Replace all epoch-scoped observations with a new empty epoch.

This resets outcomes, timestamps, the expected-failure streak, counters, and performance aggregates. Persistent scheduling state is owned outside this observation value.

pub const fn record_completion( &mut self, completion: TimerCompletion, completed_at_ns: u64, measurement: Option<TimerMeasurement>, )

Record one returned callback atomically across outcome and counters.

Performance changes only when a valid end measurement is supplied.

pub const fn record_interruption(&mut self, observed_at_ns: u64)

Record an interruption in the epoch where it becomes observable.

pub const fn record_request(&mut self)

Record a validated schedule or reconciliation request.

pub const fn record_arm(&mut self)

Record an actual one-shot provider arm.

pub const fn record_start(&mut self)

Record a non-stale callback entering logical execution.

pub const fn record_cancellation(&mut self)

Record a logical cancellation that wins arbitration.

pub const fn record_stale(&mut self)

Record a provider callback or completion rejected as stale.

pub const fn record_coalesced(&mut self)

Record scheduling demand merged into existing work.

pub const fn epoch(self) -> TimerEpoch

Return the observation epoch.

pub const fn outcomes(self) -> TimerOutcomeSnapshot

Return latest outcomes and functional failure state.

pub const fn counters(self) -> TimerCounters

Return epoch-local event counters.

pub const fn performance(self) -> TimerPerformance

Return completed callback performance aggregates.

pub const fn consecutive_expected_failures(self) -> u64

Return functional expected-failure state without rebuilding a snapshot.
