Struct tokio_retry::RetryIf

pub struct RetryIf<I, A, C>
where
    I: Iterator<Item = Duration>,
    A: Action,
    C: Condition<A::Error>,
{ /* private fields */ }

Future that drives multiple attempts at an action via a retry strategy. Retries are only attempted if the Error returned by the future satisfies a given condition.

Implementations

impl<I, A, C> RetryIf<I, A, C>

where I: Iterator<Item = Duration>, A: Action, C: Condition<A::Error>,

pub fn spawn<T: IntoIterator<IntoIter = I, Item = Duration>>( strategy: T, action: A, condition: C, ) -> RetryIf<I, A, C>

Trait Implementations

impl<I, A, C> Future for RetryIf<I, A, C>

where I: Iterator<Item = Duration>, A: Action, C: Condition<A::Error>,

type Output = Result<<A as Action>::Item, <A as Action>::Error>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
