Pipeline factory

Implementations

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

pub fn and_then<F, U>(
    self,
    factory: F
) -> PipelineFactory<Req, AndThenFactory<T, U>, 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) -> PipelineFactory<Req, ApplyMiddleware<U, T, C>, C>where
    U: Middleware<T::Service>,

Apply middleware to current service factory.

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

pub fn then<F, U>(self, factory: F) -> PipelineFactory<Req, ThenFactory<T, U>, 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 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, Res>(
    self,
    f: F
) -> PipelineFactory<Req, MapFactory<T, F, Req, Res, C>, 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
) -> PipelineFactory<Req, MapErrFactory<T, Req, C, F, E>, C>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<Req, MapInitErr<T, Req, C, F, E>, C>where
    Self: Sized,
    F: Fn(T::InitError) -> E + Clone,

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

Trait Implementations
