Trait failsafe::failure_policy::FailurePolicy

pub trait FailurePolicy {
    fn record_success(&mut self);
    fn mark_dead_on_failure(&mut self) -> Option<Duration>;
    fn revived(&mut self);

    fn or_else<R>(self, rhs: R) -> OrElse<Self, R>
    where
        Self: Sized,
    { ... }
}

A FailurePolicy is used to determine whether or not the backend died.

Required Methods

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.

Provided Methods

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

Creates a FailurePolicy which uses both self and rhs.
