Struct ResponseFuture 

pub struct ResponseFuture<S1, S2, Request, F = OnError>
where
    S1: Service<Request>,
    S2: Service<Request, Response = <S1 as Service<Request>>::Response>,
    F: FallbackPolicy<<S1 as Service<Request>>::Response>,
    S1::Error: Into<BoxedError>,
    S2::Error: Into<BoxedError>,
{ /* private fields */ }

Future that completes either with the first service’s successful response, or with the second service’s response.

Trait Implementations

impl<S1, S2, Request, F> Debug for ResponseFuture<S1, S2, Request, F>

where S1: Service<Request>, S2: Service<Request, Response = <S1 as Service<Request>>::Response> + Debug, F: FallbackPolicy<<S1 as Service<Request>>::Response>, S1::Error: Into<BoxedError>, Request: Debug, S1::Future: Debug, S2::Future: Debug, S2::Error: Into<BoxedError>,

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

Formats the value using the given formatter.

impl<S1, S2, Request, F> Future for ResponseFuture<S1, S2, Request, F>

where S1: Service<Request>, S2: Service<Request, Response = <S1 as Service<Request>>::Response>, F: FallbackPolicy<<S1 as Service<Request>>::Response>, S1::Error: Into<BoxedError>, S2::Error: Into<BoxedError>,

type Output = Result<<S1 as Service<Request>>::Response, Box<dyn Error + Sync + Send>>

The type of value produced on completion.

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

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