Struct SuccessRateOverTimeWindow

pub struct SuccessRateOverTimeWindow<BACKOFF> { /* private fields */ }

A policy based on an exponentially-weighted moving average success rate over a time window. A moving average is used so the success rate calculation is biased towards more recent requests.

Trait Implementations

impl<BACKOFF: Debug> Debug for SuccessRateOverTimeWindow<BACKOFF>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SuccessRateOverTimeWindow<EqualJittered>

fn default() -> Self

Returns the “default value” for a type.

impl<BACKOFF> FailurePolicy for SuccessRateOverTimeWindow<BACKOFF>

where BACKOFF: Iterator<Item = Duration> + Clone,

fn record_success(&mut self)

Invoked when a request is successful.

fn mark_dead_on_failure(&mut self) -> Option<Duration>

Invoked when a non-probing request fails. If it returns Some(Duration), the backend will mark as the dead for the specified Duration.

fn revived(&mut self)

Invoked when a backend is revived after probing. Used to reset any history.

fn or_else<R>(self, rhs: R) -> OrElse<Self, R>

where Self: Sized,

Creates a FailurePolicy which uses both self and rhs.
