Struct ntex_service::dev::Map

pub struct Map<A, F, Req, Res> { /* private fields */ }

Service for the map combinator, changing the type of a service’s response.

This is created by the ServiceExt::map method.

Trait Implementations

impl<A, F, Req, Res> Clone for Map<A, F, Req, Res>where A: Clone, F: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A, F, Req, Res> Service<Req> for Map<A, F, Req, Res>where A: Service<Req>, F: Fn(A::Response) -> Res,

type Response = Res

Responses given by the service.

type Error = <A as Service<Req>>::Error

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

type Future<'f> where Self: 'f, Req: 'f = MapFuture<'f, A, F, Req, Res>

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<'_>) -> Poll<()>

Shutdown service.

fn call<'a>(&'a self, req: Req, ctx: ServiceCtx<'a, Self>) -> Self::Future<'a>

Process the request and return the response asynchronously.

fn map<F, Res>(self, f: F) -> Map<Self, F, Req, Res>where Self: Sized, F: Fn(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, F, E>where Self: Sized, F: Fn(Self::Error) -> E,

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