Trait Implementations

impl<V1: Clone, V2: Clone, V3: Clone, V4: Clone, V1R, V2R, V3R, V4R> Clone for VariantService4<V1, V2, V3, V4, V1R, V2R, V3R, V4R>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V1, V2, V3, V4, V1R, V2R, V3R, V4R> Service<Variant4<V1R, V2R, V3R, V4R>> for VariantService4<V1, V2, V3, V4, V1R, V2R, V3R, V4R> where
    V1: Service<V1R>,
    V2: Service<V2R, Response = V1::Response, Error = V1::Error>,
    V3: Service<V3R, Response = V1::Response, Error = V1::Error>,
    V4: Service<V4R, Response = V1::Response, Error = V1::Error>, 

type Response = V1::Response

Responses given by the service.

type Error = V1::Error

Errors produced by the service.

type Future = ServiceResponse<V1::Future, V2::Future, V3::Future, V4::Future>

The future response value.

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

Returns Ready when the service is able to process requests.

fn poll_shutdown(&self, cx: &mut Context<'_>, is_error: bool) -> Poll<()>

Shutdown service.

fn call(&self, req: Variant4<V1R, V2R, V3R, V4R>) -> Self::Future

Process the request and return the response asynchronously.

fn map<F, Res>(self, f: F) -> Map<Self, F, Req, Res> where
    F: FnMut(Self::Response) -> Res, 

Map this service’s output to a different type, returning a new service of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErr<Self, Req, F, E> where
    F: Fn(Self::Error) -> E, 

Map this service’s error to a different error, returning a new service.
