Struct CachingProxyNodeClient 

pub struct CachingProxyNodeClient<NC> { /* private fields */ }

Node client wrapper around another node client that caches some data for better performance and proxies other requests through.

NOTE: Archived segment acknowledgement is ignored in this client, all subscriptions are acknowledged implicitly and immediately. NOTE: Subscription messages that are not processed in time will be skipped for performance reasons!
