rsocket

rsocket is a WebSocket protocol implementation written from scratch in Rust, starting at raw TCP sockets.
It implements the full WebSocket lifecycle, including the HTTP upgrade handshake, frame encoding/decoding, masking, and control frames.

The system supports concurrent multi-client connections and includes a real-time chat interface to demonstrate protocol correctness under load.
No external WebSocket libraries are used—everything is built to understand protocol internals, concurrency, and network-level behavior.
