What are the best practices for using Tokio in Rust?

When using Tokio in Rust, it's important to follow best practices like avoiding blocking calls, using async functions effectively, and managing tasks properly.

Can you explain why blocking calls are a problem?

Blocking calls can prevent the Tokio runtime from scheduling other tasks, leading to performance bottlenecks and reduced concurrency.

What should I do instead of blocking calls?

Instead of blocking calls, use asynchronous versions of functions, such as tokio::fs for file operations or tokio::net for networking.

How can I manage tasks effectively in Tokio?

You can manage tasks effectively by using tokio::spawn to run tasks concurrently and JoinHandle to await their completion.

Are there any tools to help with debugging Tokio applications?

Yes, tools like tokio-console can help you visualize and debug your Tokio applications by providing insights into task states and performance.
