cursor rules for rust

[z3roai]

Hi team 👋

I am Rustacean.

I’d like to request the addition of a .cursorrules configuration specifically for Rust projects.

📌 Problem
Currently, there isn’t a template or rule set in this repository for Rust. Given the growing adoption of Rust in backend systems, web servers (e.g., Actix, Axum), CLI tools, and systems-level applications, having a standardized .cursorrules file would significantly help Rust developers use Cursor AI more effectively and idiomatically.

✅ Suggested Contents
The Rust rules could cover:

Idiomatic syntax and formatting preferences

Async best practices (with Tokio, async/await)

Error handling via Result and the ? operator

Code organization (lib.rs, main.rs, modules)

Trait usage, generics, and lifetimes

Common patterns for clippy, rustfmt, and testing (#[test])

Thanks for your awesome work on this repo! Looking forward to your thoughts.

Best regards.
