Module server 

The live WebSocket cable server: an axum ws upgrade handler that speaks the ActionCable wire protocol, a ChannelRegistry routing subscriptions to Channel handlers, a heartbeat ping loop, and a pub/sub bridge so broadcasts reach subscribed clients.

Structs

ChannelRegistry

Functions

handle_socket

Drive a single upgraded WebSocket connection: greet with welcome, ping on a heartbeat, and dispatch inbound ActionCable frames until the socket closes.

route

A Router mounting the cable endpoint at /cable, backed by registry.

ws_handler

axum handler that upgrades a request to a cable WebSocket connection.
