Implementations

impl<T: ServiceFactory<Req, C>, Req, C> ServiceChainFactory<T, Req, C>

pub fn and_then<F, U>( self, factory: F ) -> ServiceChainFactory<AndThenFactory<T, U>, Req, C>

where Self: Sized, F: IntoServiceFactory<U, T::Response, C>, U: ServiceFactory<T::Response, C, Error = T::Error, InitError = T::InitError>,

Call another service after call to this one has resolved successfully.

pub fn apply<U>( self, tr: U ) -> ServiceChainFactory<ApplyMiddleware<U, T, C>, Req, C>

where U: Middleware<T::Service>,

Apply middleware to current service factory.

Short version of apply(middleware, chain_factory(...))

pub fn apply_fn<F, R, In, Out, Err>( self, f: F ) -> ServiceChainFactory<ApplyFactory<T, Req, C, F, R, In, Out, Err>, In, C>

where F: Fn(In, Pipeline<T::Service>) -> R + Clone, R: Future<Output = Result<Out, Err>>, T: ServiceFactory<Req, C>, Err: From<T::Error>,

Apply function middleware to current service factory.

Short version of apply_fn_factory(chain_factory(...), fn)

pub fn then<F, U>( self, factory: F ) -> ServiceChainFactory<ThenFactory<T, U>, Req, C>

where Self: Sized, C: Clone, F: IntoServiceFactory<U, Result<T::Response, T::Error>, C>, U: ServiceFactory<Result<T::Response, T::Error>, C, Error = T::Error, InitError = T::InitError>,

Create chain factory to chain on a computation for when a call to the service finished, passing the result of the call to the next service U.

Note that this function consumes the receiving factory and returns a wrapped version of it.

pub fn map<F, Res>( self, f: F ) -> ServiceChainFactory<MapFactory<T, F, Req, Res, C>, Req, C>

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

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

pub fn map_err<F, E>( self, f: F ) -> ServiceChainFactory<MapErrFactory<T, Req, C, F, E>, Req, C>

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

Map this service’s error to a different error.

pub fn map_init_err<F, E>( self, f: F ) -> ServiceChainFactory<MapInitErr<T, Req, C, F, E>, Req, C>

where Self: Sized, F: Fn(T::InitError) -> E + Clone,

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

pub async fn pipeline( &self, cfg: C ) -> Result<Pipeline<T::Service>, T::InitError>

where Self: Sized,

Create and return a new service value asynchronously and wrap into a container
