Trait Implementations

source

impl<LEFT: Debug, RIGHT: Debug> Debug for OrElse<LEFT, RIGHT>

source

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

Formats the value using the given formatter. Read more

source

impl<LEFT, RIGHT> FailurePolicy for OrElse<LEFT, RIGHT>where
LEFT: FailurePolicy,
RIGHT: FailurePolicy,

source

fn record_success(&mut self)

Invoked when a request is successful.

source

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

source

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

Creates a FailurePolicy which uses both self and rhs.
