What is the Result type in Rust?

Can you explain what the Result type is in Rust?

The Result type in Rust is an enum that represents either success (Ok) or failure (Err) of an operation.

How do I use the Result type in my functions?

You can return a Result type from your functions to indicate success or failure, using Ok for success and Err for errors.

Can you give me an example of a function that uses Result?

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)
    }
}

What are some common patterns for handling Result types?

Common patterns include using match statements, the ? operator for error propagation, and methods like unwrap or expect.
