Trait Implementations

impl<T, Req, F, In, Out, Err> Clone for Apply<T, Req, F, In, Out, Err>

where T: Clone, F: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, Req, F, In, Out, Err> Debug for Apply<T, Req, F, In, Out, Err>

where T: Debug,

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

Formats the value using the given formatter.

impl<T, Req, F, In, Out, Err> Service<In> for Apply<T, Req, F, In, Out, Err>

where T: Service<Req>, F: AsyncFn(In, &ApplyCtx<'_, T>) -> Result<Out, Err>, Err: From<T::Error>,

type Response = Out

Responses given by the service.

type Error = Err

Errors produced by the service when polling readiness or executing call.

async fn ready(&self, ctx: ServiceCtx<'_, Self>) -> Result<(), Err>

Returns when the service is ready to process requests.

async fn call( &self, req: In, ctx: ServiceCtx<'_, Self>, ) -> Result<Self::Response, Self::Error>

Processes a request and returns the response asynchronously.

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

Polls the service from the current async task.

async fn shutdown(&self)

Shuts down the service.

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

where Self: Sized, F: Fn(Self::Response) -> Res,

Maps this service’s output to a different type, returning a new service.

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

where Self: Sized, F: Fn(Self::Error) -> E,

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