Fortran - Errors and error handling - Part 4 - Using an Either type

Read Original

This technical article discusses advanced error handling in Fortran, focusing on non-fatal errors. It critiques simple optional return values and proposes using an 'Either' type (e.g., point_or_error_t) to return either a successful result (a parsed point) or a descriptive error object, providing a robust alternative to exceptions or program halts.
