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.

Research direction
Examine the existing redigo codebase to understand the current low level pubsub API and connection handling. Review the discussion in the issue's comments (if any) and consider the optional features. Proposed changes would likely involve creating new types and functions in a new file, e.g., pubsub.go, that wrap the existing Conn and PubSubConn. The implementation should follow the pattern of other Go Redis clients like go redis for inspiration.
