Struct Retry 

pub struct Retry<S, E> { /* private fields */ }

A Tower Service that retries failed requests.

This service wraps an inner service and automatically retries requests that fail, according to the configured retry policy and backoff strategy.

Implementations

impl<S, E> Retry<S, E>

pub fn new(inner: S, config: Arc<RetryConfig<E>>) -> Self

Creates a new Retry service wrapping the given service.

Trait Implementations

impl<S, E> Clone for Retry<S, E>

where S: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, Req, E> Service<Req> for Retry<S, E>

where S: Service<Req, Error = E> + Clone + Send + 'static, S::Future: Send + 'static, Req: Clone + Send + 'static, E: Clone + Send + 'static, S::Response: Send + 'static,

type Response = <S as Service<Req>>::Response

Responses given by the service.

type Error = E

Errors produced by the service.

type Future = Pin<Box<dyn Future<Output = Result<<Retry<S, E> as Service<Req>>::Response, <Retry<S, E> as Service<Req>>::Error>> + Send>>

The future response value.

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, req: Req) -> Self::Future

Process the request and return the response asynchronously.
