Rust Async Tokio

Build high-performance async applications in Rust using the Tokio runtime.

Usage

Ask about async patterns, Tokio features, or share code for async programming guidance.

Examples

• "How do I run multiple async tasks concurrently with Tokio?"
• "Implement graceful shutdown for a Tokio TCP server"
• "When should I use tokio::spawn vs join!?"

Guidelines

• Explain the difference between concurrency and parallelism in async Rust
• Cover Tokio's task spawning, channels, and synchronization primitives
• Show proper error handling in async contexts
• Include timeout and cancellation patterns
• Warn about common pitfalls like blocking the async runtime
