Rustfuif

Fronted

Rustfuif is an open source stock market party implementation.

Concept

A stock market party is an event where the prices of the beverages rise and fall based upon demand.

All prices are updated on certain intervals. Sometimes there's a stock market crash, which causes all beverages to drop to their lowest possible price.

You can invite other players(bars/youth clubs) to join your stock market party. They will then have an influence on your prices, and you on theirs.

Features

• automatic price updates(using websockets) based on demand
• some nice graphs
• history of purchases and prices
• admin panel to see connected users, active games, total games, server status, ...
• completely optional cache (can be toggled at runtime)

Development

docker-compose up

# cargo install cargo-watch
cargo watch -x run

Observability

• /metrics constains prometheus metrics
• /health returns http 200
• /stats shows the following live stats:
  • total handled requests
  • total server errors (http response code >= 500)
  • active websocket connections
  • active games
  • active db connections
  • idle db connections
• more logging can be acquired by setting the RUST_LOG to a lower loglevel, eg:
  • RUST_LOG="actix_server=info,actix_web=trace,rustfuif=trace"
  • RUST_LOG="debug"
  • ...
• jaeger tracing using:
  • tokio-rs/tracing
  • tracing-opentelemetry
  • OutThereLabs/actix-web-opentelemetry
