Fortran - Errors and error handling - Part 6 - Guarantees

This technical article discusses implementing robust error handling and data guarantees in Fortran. It uses the example of a polyline type that must contain at least two points, demonstrating how to enforce this rule by making data components private and using a factory function that returns a result-or-error type. The article covers practical software engineering patterns for creating reliable APIs in a scientific programming context.
