Struct gotham::pipeline::PipelineBuilder

pub struct PipelineBuilder<T> where
    T: NewMiddlewareChain,  { /* fields omitted */ }

Allows a pipeline to be defined by adding NewMiddleware values, and building a Pipeline.

Examples

new_pipeline()
    .add(MiddlewareOne)
    .add(MiddlewareTwo)
    .add(MiddlewareThree)
    .build();

The pipeline defined here is invoked in this order:

(&mut state) → MiddlewareOne → MiddlewareTwo → MiddlewareThree → handler (provided later, when building the router)

Implementations

impl<T> PipelineBuilder<T> where
    T: NewMiddlewareChain, 

pub fn build(self) -> Pipeline<T> where
    T: NewMiddlewareChain, 

Builds a Pipeline, which contains all middleware in the order provided via add and is ready to process requests via a NewHandler provided to Pipeline::call.

pub fn add<M>(self, m: M) -> PipelineBuilder<(M, T)> where
    M: NewMiddleware,
    M::Instance: Send + 'static,
    Self: Sized, 

Adds a NewMiddleware which will create a Middleware during request dispatch.
