Pipeline factory

Implementations

impl<T: ServiceFactory> PipelineFactory<T>

pub fn and_then<F, U>(
    self,
    factory: F
) -> PipelineFactory<impl ServiceFactory<Request = T::Request, Response = U::Response, Error = T::Error, Config = T::Config, InitError = T::InitError, Service = impl Service<Request = T::Request, Response = U::Response, Error = T::Error> + Clone> + Clone> where
    Self: Sized,
    T::Config: Clone,
    F: IntoServiceFactory<U>,
    U: ServiceFactory<Config = T::Config, Request = T::Response, Error = T::Error, InitError = T::InitError>, 

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

pub fn and_then_apply_fn<U, I, F, Fut, Res, Err>(
    self,
    factory: I,
    f: F
) -> PipelineFactory<impl ServiceFactory<Request = T::Request, Response = Res, Error = Err, Config = T::Config, InitError = T::InitError, Service = impl Service<Request = T::Request, Response = Res, Error = Err> + Clone> + Clone> where
    Self: Sized,
    T::Config: Clone,
    I: IntoServiceFactory<U>,
    U: ServiceFactory<Config = T::Config, InitError = T::InitError>,
    F: Fn(T::Response, &U::Service) -> Fut + Clone,
    Fut: Future<Output = Result<Res, Err>>,
    Err: From<T::Error> + From<U::Error>, 

Apply function to specified service and use it as a next service in chain.

Short version of pipeline_factory(...).and_then(apply_fn_factory(...))

pub fn apply<U>(self, tr: U) -> PipelineFactory<ApplyTransform<U, T>> where
    U: Transform<T::Service>, 

Apply transform to current service factory.

Short version of apply(transform, pipeline_factory(...))

pub fn then<F, U>(
    self,
    factory: F
) -> PipelineFactory<impl ServiceFactory<Request = T::Request, Response = U::Response, Error = T::Error, Config = T::Config, InitError = T::InitError, Service = impl Service<Request = T::Request, Response = U::Response, Error = T::Error> + Clone> + Clone> where
    Self: Sized,
    T::Config: Clone,
    F: IntoServiceFactory<U>,
    U: ServiceFactory<Config = T::Config, Request = Result<T::Response, T::Error>, Error = T::Error, InitError = T::InitError>, 

Create NewService 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 pipeline and returns a wrapped version of it.

pub fn map<F, R>(self, f: F) -> PipelineFactory<MapServiceFactory<T, F, R>> where
    Self: Sized,
    F: FnMut(T::Response) -> R + 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
) -> PipelineFactory<MapErrServiceFactory<T, F, E>> where
    Self: Sized,
    F: Fn(T::Error) -> E + Clone, 

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

pub fn map_init_err<F, E>(self, f: F) -> PipelineFactory<MapInitErr<T, F, E>> where
    Self: Sized,
    F: Fn(T::InitError) -> E + Clone, 

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