Rust bb8/websocket/Redis Pubsub demo

This is an example of how you might run a Rust server, using Redis as Pubsub (it is extending the example in https://github.com/seanmonstar/warp/blob/master/examples/websockets_chat.rs).

The value of this is being able to run multiple Rust websocket servers, which are able to exchange messages via the Redis Pubsub so that a user connected to server A can receive messages from a user connected to server B.

Running

To run this, just have a Redis server running on port 6379 on your local machine, then:

export PORT=3030
cargo run

and if you want to run a separate server, to observe the servers communicating via the Pubsub just run another instance with a different port.

export PORT=3031
cargo run

Testing

Personally, I like to copy the code from https://blog.scottlogic.com/2019/07/23/Testing-WebSockets-for-beginners.html and use it in my browser console. Be warned, in the tutorial the snippet

ws.onmessage = function (e) {
console.log("From Server:"+ e.data"); <=== this last " is a typo
};

Disclaimer: There are a lot of unwraps here, consider handling these errors if you use this code as inspo/boilerplate
