Expand description

A heterogeneous list of Handle<P, _> values, where P is a pipeline type. The pipelines are borrowed and invoked in order to serve a request.

Implemented using nested tuples, with () marking the end of the list. The list is in the reverse order of their invocation when a request is dispatched.

That is:

(p3, (p2, (p1, ())))

will be invoked as:

(state, request)p1p2p3handler

Required methods

Invokes this part of the PipelineHandleChain, with requests being passed through to f once all Middleware in the Pipeline have passed the request through.

Implementations on Foreign Types

Part of a PipelineHandleChain which references a Pipeline and continues with a tail element.

The marker for the end of a PipelineHandleChain.
