What are the different error types in Rust's async programming?
In Rust's async programming, common error types include Box<dyn Error>, std::io::Error, and custom error types using the thiserror crate.
Can you explain how to create a custom error type?
Sure! You can create a custom error type by defining a struct and implementing the std::fmt::Display and std::error::Error traits.
What is the purpose of using Box<dyn Error>?
Box<dyn Error> allows you to return different error types from a function, providing flexibility in error handling.
How do I handle errors in async functions?
You can use the ? operator to propagate errors in async functions, or handle them using match or if let statements.
