[tech-andgar]

Add a new method that returns a record with success and error values for destructuring.
Include documentation and tests for the new functionality.

unwrap would be a better name.
failure to maintain consistency in nomenclature.

final (:success, :failure) = result.unwrap();

@wellgenio Thanks for the feedback!

I would prefer to avoid unwrap. In many ecosystems (like Rust or Swift), unwrap implies "get the value or crash/throw."

Since this method is safe and simply splits the result, I suggest unpack (or toRecord). It describes the action of destructuring without implying the risk of a runtime exception.
