Rust Patterns

Purpose

Implement Rust-specific patterns — async/await with tokio, error handling with thiserror/anyhow, serde for JSON, ownership patterns, concurrency with Arc/RwLock, and API handler patterns with Axum.

Agent Protocol

Trigger

User request includes: Rust async, Rust tokio, Rust error handling, Rust serde, Rust ownership, Rust Arc, Rust Mutex, Rust pattern, Rust API handler.

Input Context

• Async runtime (tokio)
• Web framework (Axum, Actix-web)
• Error pattern needed (thiserror, anyhow)
• Concurrency model (Arc, channels, actor)

Output Artifact

Code examples for the requested pattern — async handler, error type, serialization, shared state.
