Struct TimerCounters 

pub struct TimerCounters { /* private fields */ }

Registration-local timer event counters.

Metrics owns arithmetic and actual-overflow tracking; the registry is the sole writer of these named events. Completed work merges its four classified outcomes. Getters return inert copies, not mutation authority.

Check the parent snapshot’s full registration identity before using MeasurementCounter::delta_since; epoch equality alone does not prove continuity. Use checked counter operations rather than inferring overflow from a numeric cap: an exact u128::MAX remains distinguishable from overflow.

Implementations

impl TimerCounters

pub const fn schedule_requests(self) -> MeasurementCounter

Return validated activation and reconciliation requests.

pub const fn wakeups_armed(self) -> MeasurementCounter

Return ordinary or scheduler provider one-shots armed.

pub const fn work_dispatched(self) -> MeasurementCounter

Return immediate watchdog work one-shots dispatched.

pub const fn scheduler_started(self) -> MeasurementCounter

Return accepted watchdog scheduler callbacks.

pub const fn work_started(self) -> MeasurementCounter

Return accepted consumer-work callbacks.

pub const fn work_completed(self) -> MeasurementCounter

Return consumer work whose completion accounting committed.

Merge the four classified counters, preserving actual-overflow quality.

pub const fn succeeded(self) -> MeasurementCounter

Return successful-work completions.

pub const fn no_work(self) -> MeasurementCounter

Return valid no-work completions.

pub const fn retryable_failure(self) -> MeasurementCounter

Return retryable expected-failure completions.

pub const fn invariant_failure(self) -> MeasurementCounter

Return invariant or terminal-failure completions.

pub const fn cancelled(self) -> MeasurementCounter

Return logical cancellations that changed authoritative state.

pub const fn stale_wakeups(self) -> MeasurementCounter

Return rejected ordinary or scheduler callback generations.

pub const fn stale_work(self) -> MeasurementCounter

Return rejected watchdog work generations.

pub const fn coalesced(self) -> MeasurementCounter

Return scheduling demand satisfied without another logical arm.

pub const fn unacknowledged(self) -> MeasurementCounter

Return confirmed ordinary deliveries dropped without completion and committed Watchdog dispatches retired by their successor without completion.
