Struct ServiceRegistry 

pub struct ServiceRegistry { /* private fields */ }

Service registry backed by the NDN namespace.

Services advertise under /local/services/<name>/info (capabilities) and /local/services/<name>/alive (heartbeat with short FreshnessPeriod). Discovery is a CanBePrefix Interest for /local/services.

This in-memory implementation is used for testing and single-process deployments. A production implementation would publish and fetch Data packets via the engine.
