Implementations§

Source§

impl ExecutionTimer

Source

pub const fn new(config: Option<ExecutionTimerConfig>) -> Self

Construct a new timer with the provided configuration.

Source

pub const fn reset(&mut self)

Reset the timer state to its initial configuration without recording a start instant.

Source

pub const fn start(&mut self, now: Duration)

Reset any prior state and record the start instant.

Source

pub const fn config(&self) -> Option<ExecutionTimerConfig>

Returns the timer configuration.

Source

pub const fn limit(&self) -> Option<Duration>

Returns the configured limit.

Source

pub const fn last_elapsed(&self) -> Duration

Returns the last elapsed duration recorded by a check.

Source

pub fn tick(&mut self, work_units: u32, now: Duration) -> Result<(), LimitError>

Increment work units and run the periodic limit check when necessary.

Source

pub fn check_now(&mut self, now: Duration) -> Result<(), LimitError>

Force an immediate check against the configured deadline.

Source

pub fn elapsed(&self, now: Duration) -> Option<Duration>

Compute elapsed time relative to the recorded start, if available.

Source

pub const fn resume_from_elapsed(&mut self, now: Duration, elapsed: Duration)

Realign the timer start so that a previously consumed elapsed duration is preserved while ignoring any wall-clock time that passed during a suspension window.
