init(upstream: Upstream, receiveSubscription: ((Subscription) -> Bool)? = nil, receiveOutput: ((Upstream.Output) -> Bool)? = nil, receiveCompletion: ((Subscribers.Completion<Publishers.Breakpoint<Upstream>.Failure>) -> Bool)? = nil)

Parameters

upstream

The publisher from which this publisher receives elements.

receiveSubscription

A closure that executes when the publisher receives a subscription, and can raise a debugger signal by returning a true Boolean value.
