Description

Add high-level pubsub API that accomplishes the following goals:

  • Hides receive loop from application, possibly by calling application supplied function to handle notifications.
  • Uses context.Context to cancel subscriptions.
  • Provides way for application to backfill after dialing and subscribing.
  • Uses ping to check for live connection and server.
  • Optional: support using pool to get connections.
  • Optional: subscribe/unsubscribe after running.

Contributor guide

Research direction
Review the existing PubSubConn and Receive methods in redigo. Design a wrapper that accepts a handler function, uses context for cancellation, and supports backfill via initial data inclusion. Investigate ping mechanism and optional pool integration.
