Code Style

• Rust with no minimum supported version
• Actix-web for HTTP services
• SQLx for MySQL and SQLite
• A mix of wreq and reqwest for Rust HTTP clients
• Never use println! or eprintln! outside of tests; use log crate macros instead
• TypeScript with Nx, React, Vite, Zustand, and Three.js
• Use two spaces for indentation

File Layout

Organize for top-to-bottom reading. Important things first, details later.

• Constants at the top (after imports)
• Structs/enums next; outer structs above inner sub-structs
• API types in order: Request, Response, Error
• In impl blocks: constructors first, then public methods, then private helpers
• Private helpers go below the methods that call them
• Among helpers: meatier logic above leaf-level formatters
