Creates a breakpoint publisher with the provided upstream publisher and breakpoint-raising closures.

Declaration

init(upstream: Upstream, receiveSubscription: ((any 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.
