Struct TimerSnapshot 

pub struct TimerSnapshot { /* private fields */ }

Canonical provider-neutral operator snapshot for one logical timer.

Implementations

impl TimerSnapshot

pub const fn identity(&self) -> &TimerIdentity

Return the stable structured identity.

pub const fn registration_id(&self) -> TimerRegistrationId

Return the inert identity of this registration’s counter lifetime.

Cancellation, rescheduling and completion preserve it. Unregistering and registering again changes it, even within the same runtime epoch. Compare only snapshots from the same canister. This value grants no timer-control authority and cannot be used to reconstruct a registration.

pub const fn policy(&self) -> TimerPolicy

Return the configured scheduling policy.

pub const fn lifetime(&self) -> DeclarationLifetime

Return whether the declaration remains after terminal stop.

pub const fn state(&self) -> TimerRuntimeStateSnapshot

Return the closed policy-specific runtime state.

pub const fn scheduling_mode(&self) -> TimerSchedulingMode

Return the effective scheduling mode.

A new declaration starts with its configured policy mode. Later requests and completed directives update this value, including after the declaration becomes inactive.

pub const fn latest_directive(&self) -> Option<TimerDirectiveSnapshot>

Return the latest completed ordinary directive.

pub const fn latest_requested_delay_ns(&self) -> Option<u64>

Return the latest requested relative delay.

pub const fn latest_armed_delay_ns(&self) -> Option<u64>

Return the latest relative delay whose provider arm committed.

pub const fn next_deadline_ns(&self) -> Option<u64>

Return the next authoritative absolute deadline.

pub fn registration_status(&self) -> TimerRegistrationStatus

Return a portable registration projection.

pub const fn process_condition(&self) -> TimerProcessCondition

Return an operator-facing condition derived from coherent state.

pub const fn generation(&self) -> Option<u64>

Return the latest authoritative callback generation.

Scheduling changes this value. Use Self::registration_id to check counter continuity across observations.

pub const fn observability(&self) -> TimerObservabilitySnapshot

Return registration-scoped outcomes, counters, and measurements.
