How can I handle errors effectively in Rust?

In Rust, you can handle errors using the Result and Option types. Would you like to know more about these?

Yes, please explain the Result type.

The Result type is an enum that represents either success (Ok) or failure (Err). You can use pattern matching to handle both cases.

Can you give me an example of using Result in a function?

Sure! Here's a simple example:

fn divide(a: f64, b: f64) -> Result<f64, String> {
    if b == 0.0 {
        Err("Cannot divide by zero".to_string())
    } else {
        Ok(a / b)
    }
}

This function returns a Result indicating success or an error message.

What about error propagation in Rust?

You can use the ? operator to propagate errors. It simplifies error handling by returning early if an error occurs.
