Trait Implementations

impl<F, Fut, Req, Res, Err, FShut> Clone for FnService<F, Fut, Req, Res, Err, FShut> where
    F: Fn(Req) -> Fut + Clone,
    Fut: Future<Output = Result<Res, Err>>,
    FShut: FnOnce() + Clone, 

pub fn clone(&self) -> FnService<F, Fut, Req, Res, Err, FShut>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F, Fut, Req, Res, Err> IntoService<FnService<F, Fut, Req, Res, Err, fn()>> for F where
    F: Fn(Req) -> Fut,
    Fut: Future<Output = Result<Res, Err>>, 

pub fn into_service(self) -> FnService<F, Fut, Req, Res, Err, fn()>

Convert to a Service

impl<F, Fut, Req, Res, Err, FShut> Service for FnService<F, Fut, Req, Res, Err, FShut> where
    F: Fn(Req) -> Fut,
    Fut: Future<Output = Result<Res, Err>>,
    FShut: FnOnce(), 

type Request = Req

Requests handled by the service.

type Response = Res

Responses given by the service.

type Error = Err

Errors produced by the service.

type Future = Fut

The future response value.

pub fn poll_ready(
    &self,
    &mut Context<'_>
) -> Poll<Result<(), <FnService<F, Fut, Req, Res, Err, FShut> as Service>::Error>>

Returns Ready when the service is able to process requests.

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

Shutdown service.

pub fn call(
    &self,
    req: Req
) -> <FnService<F, Fut, Req, Res, Err, FShut> as Service>::Future

Process the request and return the response asynchronously.

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

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