public interface ConversionResult
This is a marker interface used as the result of methods that convert or cast values from one type to another. It is implemented by AtomicValue, which indicates a successful conversion, and by ValidationFailure, which indicates an unsuccessful conversion. An unsuccessful conversion does not throw an exception because exceptions are expensive and should not be used on success paths. For example when validating a union, conversion failures are to be expected.

- Returns:
- the atomic value that results from the conversion if the conversion was successful
- Throws:
ValidationException
- if the conversion was not successful
