Multi-threaded chat server in Rust with Tokio

High performant chat server to skill up in Rust and Tokio.

Notes:

• Each incoming request spins up a tokio task => the server can handle multiple requests at the time.
• The conversation history is the only mutable shared state between the tokio tasks.
  • So i chose to store it on the heap and protected it with a reference-counting pointer and a mutex (Arc<Mutex<Vec<(String, String)>>>).
  • I may do the message passing between tokio tasks option in the future.
• Shortcomings:
  • The client only communicates to the backend through GET requests.
  • You have to constantly renter your username.
• It is now containerized, with a clean multi-staged build for quick developement.
• To run: just run docker-compose up --build

I know the html sucks, but the focus was on the backend.
