1//! Special Function Codes Module
2//!
3//! This module is reserved for special purposes. If an organization has
4//! proprietary or custom function codes that are not part of the standard
5//! Modbus Public Function Codes, those will be declared and managed here.
6//!
7//! This allows the library to be extended for vendor-specific implementations
8//! while keeping the core public function codes compliant with the
9//! Modbus Application Protocol Specification.
