Rust Pro

What it does

This skill provides expert-level assistance with Rust backend development, specializing in modern (Rust 1.75+) features and systems-level performance. It enables AI agents to build robust services, libraries, or tooling while ensuring memory safety and optimizing for speed. The skill leverages advanced techniques like async programming and the Tokio runtime to create production-ready applications.

When to use it

• Building Rust services, libraries, or systems tooling.
• Troubleshooting ownership, lifetime, or asynchronous design challenges in Rust code.
• Optimizing performance while maintaining memory safety guarantees within a Rust project.

Key capabilities

• Modern Rust Language Features: Rust 1.75+ features (const generics, improved type inference), advanced lifetime annotations, generic associated types (GATs), pattern matching with guards, compile-time computation, macros, and module system controls.
• Ownership & Memory Management: Mastery of ownership rules, borrowing, move semantics, reference counting (Rc, Arc, weak references), smart pointers (Box, RefCell, Mutex, RwLock), memory layout optimization, RAII patterns, Phantom types, custom allocators.
• Async Programming & Concurrency: Advanced async/await patterns with Tokio runtime, stream processing, channel patterns (mpsc, broadcast, watch channels), and backpressure handling.
• Type System & Traits: Advanced trait implementations, associated types, higher-kinded types, type erasure, compile-time polymorphism, and monomorphization.
• Performance & Systems Programming: Zero-cost abstractions, SIMD programming (portable-simd), memory mapping, lock-free programming, atomic operations, cache-friendly data structures.

Example prompts

• "I'm experiencing a lifetime error in my Rust code; can you help me understand and resolve it?"
• "How can I optimize this Rust function for performance using SIMD techniques?"
• "What is the best approach to implement an asynchronous web service with Tokio and Axum?"

Tips & gotchas

• Clearly define performance, safety, and runtime constraints before starting.
• This skill is not suitable for simple scripts or situations where Rust cannot be introduced into the project.
• Familiarity with Rust syntax is expected; this skill focuses on advanced concepts and optimization.
