详细描述

Abstract base class for all transport-specific subscriber implementations.

SubscriberImpl is the intermediate layer between the generic Subscriber<T> template and a concrete transport backend (e.g. DdsSubscriberImpl, ShmSubscriberImpl). It inherits from NodeImpl and adds receive-side semantics:

• Two listen overloads: a serialised MsgCallback for network transports and a zero-copy IntraMsgCallback for the intra:// backend.
• Optional latency and sample-loss tracking via CalculateSample.
• A public is_listened flag indicating whether a listener has been installed.

注解

Concrete subclasses must implement listen(MsgCallback&&). listen(IntraMsgCallback&&) is only overridden by IntraSubscriberImpl; all other transports inherit the base no-op that logs a warning and returns false.
