Rust Error Handling

Master Rust's error handling mechanisms using Result, Option, custom error types, and popular error handling libraries for robust applications.

Result and Option

Result type for recoverable errors:

// Result<T, E> for operations that can fail
fn divide(a: f64, b: f64) -> Result<f64, String> {
    if b == 0.0 {
        Err(String::from("Division by zero"))
    } else {
        Ok(a / b)
    }
}
