A very basic chat server in Rust.

telnet 0.0.0.0 1234

Configuring the port

cargo run -- --port=9090

Support commands

To join a room

NOTE: You can only join only 1 room in the entire client lifetime.

To send message

NOTE: You'll get an error message if you attempt to send a message without joining a room.

Any random message.

• Actix WebSocket

Entities

All entities in the system are running as actors, and they include:

• User
• Server

Protocol

The communication between an external client(e.g. telnet) and the server adopts a very simple Codec which can ve found here.

Further improvements

• To handle more scale, we can leverage on actix-redis to persist user sessions to redis (possibly, a redis cluster).
