Detailed Description

General utility functions.

This header provides general utility functions used throughout OpenPFC, including string formatting, file operations, and helper functions.

Key utilities:

#include <openpfc/utils.hpp>
 
// Format strings safely
std::string msg = pfc::utils::string_format("Step %d, time = %.3f", step, time);

See also: utils/array_to_string.hpp for array formatting; utils/show.hpp for debug printing; utils/typename.hpp for type introspection; utils/field_iteration.hpp for inbox iteration helpers
