What are some best practices for error handling in Rust?

In Rust, it's essential to use the Result and Option types for error handling. This allows you to explicitly handle errors without exceptions.

Can you explain the difference between Result and Option?

Sure! Result is used for functions that can return an error, while Option is for cases where a value might be absent. Result has two variants: Ok for success and Err for failure, whereas Option has Some for a value and None for no value.

How do I propagate errors in Rust?

You can propagate errors using the ? operator. It allows you to return an error from a function if the result is an Err, simplifying error handling.

What about custom error types?

Creating custom error types in Rust is straightforward. You can define an enum that implements the std::error::Error trait, allowing you to provide more context for errors.
