SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a comprehensive, opinionated guide to modern Rust best practices, helping teams write idiomatic, safe, and maintainable Rust code across style, error handling, performance, concurrency, project organization, documentation, testing, security, and CI.

Core Features & Use Cases

Style & Naming: Enforce Rust idioms for identifiers, modules, and documentation.
Formatting & CI: Use rustfmt and cargo fmt -- --check to maintain consistent formatting in CI.
Error Handling & Concurrency: Promote Result-based error handling, proper error context, and safe concurrency patterns.
Project Structure & DX: Recommend Cargo workspace usage, module layout, and documentation/testing conventions.

Quick Start

Initialize a Rust project with a typical layout and apply the guide by running cargo fmt -- --check, cargo test, and cargo clippy in CI to catch issues early.

FAQPage Schema

How do I enforce consistent code style across a Rust project?▼

Use `rustfmt` to standardize formatting and `cargo fmt -- --check` in CI to enforce consistency. This guide provides conventions for naming, module organization, and idiomatic Rust patterns that work across projects of any size.

What's the best way to handle errors in Rust?▼

Structure error handling around `Result` types with proper context and propagation. This guide covers idiomatic patterns for error handling, including when to use `Result`, how to provide meaningful error messages, and integrating error handling into your project workflow.

How should I organize a Rust project for maintainability?▼

Organize code with clear module boundaries, comprehensive doc comments, and Cargo workspace usage for multi-crate projects. This guide recommends project structure, documentation standards, and testing conventions that scale from small to large codebases.

Can I use this guide for concurrent Rust code?▼

Yes. The guide covers safe concurrency patterns and best practices for writing thread-safe, idiomatic Rust. It applies to projects of all domains, including those requiring concurrent or parallel processing.

What testing and CI practices does this guide recommend?▼

Run `cargo test` and `cargo clippy` in CI pipelines to catch issues early. The guide standardizes testing practices, documentation generation, and CI processes to integrate best practices into your development workflow automatically.
