Struct PipelineBuilder

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

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.
