What are the best practices for writing asynchronous code in Rust?

When writing asynchronous code in Rust, it's important to use the async and await keywords effectively. You should also consider using the tokio or async-std runtime for managing async tasks.

Can you explain how to handle errors in async Rust?

Certainly! In async Rust, you can handle errors using the Result type. It's common to use the ? operator to propagate errors in async functions.

What about performance considerations?

For performance, avoid blocking calls in async functions. Use non-blocking I/O and consider using tokio::spawn for lightweight task management.

Are there any common pitfalls to avoid?

Yes, common pitfalls include forgetting to await futures, creating too many tasks, and not managing lifetimes properly. Always ensure you understand the async context.
