Developers : 41-Utilizing the ? Operator in the Main Function

💻 Utilizing the ? Operator in the Main Function 💻

In Rust, the ? operator can now be used directly within the main function to simplify error handling, thanks to the introduction of std::process::Termination. When the ? operator is used in the main function, it allows for cleaner code by automatically propagating errors to the system. If an error occurs, it returns an error code, while successful execution continues as normal. This eliminates the need for verbose error handling logic in the main function, making it concise and easy to maintain.

📋 In this video, you’ll learn:

How to implement the ? operator in the main function
