Struct TimerCounters 

pub struct TimerCounters { /* private fields */ }

Epoch-local timer event counters.

Fields are private so all mutation preserves saturation and the completion partition. Consumer adapters read values through the accessors.

Implementations

impl TimerCounters

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_completion(&mut self, outcome: TimerCompletionOutcome)

Record one returned callback and its single completion class.

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 record_interruption(&mut self)

Record a started generation established not to have completed.

The interruption belongs to the epoch in which it is observed. It can therefore describe a generation started in an earlier epoch and has no arithmetic invariant with this epoch’s started count.

pub const fn requested(self) -> u64

Return validated scheduling requests.

pub const fn armed(self) -> u64

Return actual provider arm operations.

pub const fn started(self) -> u64

Return callbacks that entered logical execution.

pub const fn completed(self) -> u64

Return callbacks that completed accounting.

pub const fn succeeded(self) -> u64

Return successful-work completions.

pub const fn no_work(self) -> u64

Return valid no-work completions.

pub const fn retryable_failure(self) -> u64

Return retryable expected-failure completions.

pub const fn invariant_failure(self) -> u64

Return invariant or terminal-failure completions.

pub const fn cancelled(self) -> u64

Return logical cancellations that won arbitration.

pub const fn stale(self) -> u64

Return callbacks or completions rejected as stale.

pub const fn coalesced(self) -> u64

Return scheduling demands merged into existing work.

pub const fn interrupted(self) -> u64

Return incomplete generations observed in this epoch.

pub const fn completion_partition_is_valid(self) -> bool

Check that every completion belongs to exactly one outcome class.
