Struct Next

source 
pub struct Next<C>
where
    C: IntoFuture<Output = Response>,
{ /* private fields */ }
Expand description

A handle to trigger the execution of the rest of the request processing pipeline.

It is used by wrapping middlewares to delegate the processing of the request to the next middleware in the pipeline (or to the request handler).

Check out Blueprint::wrap for more information.
