Struct actix_service::dev::Map

pub struct Map<A, F, Response> { /* fields omitted */ }

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, Response> Clone for Map<A, F, Response> 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, Response> Service for Map<A, F, Response> where
    A: Service,
    F: FnMut(A::Response) -> Response + Clone, 

type Request = A::Request

Requests handled by the service.

type Response = Response

Responses given by the service.

type Error = A::Error

Errors produced by the service.

type Future = MapFuture<A, F, Response>

The future response value.

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

Returns Ready when the service is able to process requests.

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

Process the request and return the response asynchronously.

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

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.
