Type Alias InnerChain 

pub(crate) type InnerChain<T, R> = Vec<Box<dyn Handler<T, R> + Send>>;

Inner chain type.

This holds all handlers, which were chained together. Handlers are traversed in order.

Each handler needs to implement the Handler trait and be Send, because the chain is traversed concurrently and the handlers can be sent between threads.
