An example of an AI chatbot conversation about best practices for async programming in Rust.
What are the best practices for using async in Rust?
When using async in Rust, it's important to use the async and await keywords properly, manage lifetimes, and avoid blocking the executor.
Can you explain how to handle errors in async functions?
Certainly! You can use the Result type to handle errors in async functions, just like in synchronous Rust. Make sure to propagate errors using the ? operator.
What libraries should I consider for async programming in Rust?
Popular libraries include tokio for async runtime, async-std for async standard library features, and reqwest for making HTTP requests.
How do I test async functions in Rust?
You can use the tokio test attribute to write async tests. Just annotate your test function with #[tokio::test].
