trait HandlerWrite[-Out] extends AnyRef
Represents the "downstream" of a handler.
Whenever a handler is told to push
or finish
, it uses a HandlerWrite to receive its output.
A HandlerWrite could be an object that collects the values to a buffer which you can manually inspect later (see BoundHandler.ToBuilder),
or a wrapper around some secondary Handler i.e. the next transformation step.
- Out
The output event type from the upstream handler, which acts as the input to this receiver

Abstract Value Members
- abstract def push(out: Out): Signal
Handle a single output from the upstream handler, signalling whether or not that upstream should continue emitting values.

- out
The value from the upstream handler
- returns
A "signal" indicating whether this handler wants to continue receiving inputs afterward
