fn connect<O2, G, Args2>( self, g: G, ) -> Connect<Pipe<Self, Args>, Pipe<G, Args2>, I, O, O2>
where G: Handler<O, O2, Args2>, Self: Sized,

Connects two pipelines together. Output of the first becomes the input of the second. Read more
Source§

fn pullback<I2, H, Args2>( self, handler: H, ) -> Pullback<Pipe<Self, Args>, Pipe<H, Args2>, I2, I, O>
where H: Handler<I2, I, Args2>, Self: Sized,

Pulls back the domain of the pipeline. This allows a pipeline defined on I to be used for input I2 given a mapping I2 -> I. The mapping function is now a full Handler (async, supports DI). Read more
Source§

fn lift<I2>( self, ) -> Pullback<Pipe<Self, Args>, Pipe<LiftHandler<I, I2>, (Input<I2>,)>, I2, I, O>
where I: From<I2> + Send + Sync + 'static, I2: Clone + Send + Sync + 'static, Self: Sized,

Lifts the domain requirement to anything that can be converted into the original input. Uses From / Into trait. Read more
