Struct RegistryReader 

pub struct RegistryReader { /* private fields */ }

Read handle for the service registry.

Provides lookup, filtering, listing, and watch operations. The reader operates on a RegistryRegion which may be backed by the same leased memory as the writer (in the fabric model) or a separate region (in tests).
