Quick Reference (30 seconds)

Rust 1.92+ Development Specialist with deep patterns for high-performance, memory-safe applications.

Auto-Triggers: .rs, Cargo.toml, async/await, Tokio, Axum, SQLx, serde, lifetimes, traits

Core Use Cases:

• High-performance REST APIs and microservices
• Memory-safe concurrent systems
• CLI tools and system utilities
• WebAssembly applications
• Low-latency networking services

Quick Patterns:

Axum REST API: Create Router with route macro chaining path and handler. Add with_state for shared state. Bind TcpListener with tokio::net and serve with axum::serve.

Async Handler with SQLx: Define async handler function taking State extractor for AppState and Path extractor for id. Use sqlx::query_as! macro with SQL string and bind parameters. Call fetch_optional on pool, await, and use ok_or for error conversion. Return Json wrapped result.
