mabi-modbus 1.4.0

//! Data types and byte order support for Modbus register conversions.
//!
//! This module provides:
//! - `RegisterDataType`: Supported data types for Modbus registers
//! - `WordOrder`: Byte ordering configurations for multi-register values
//! - `RegisterConverter`: Type-safe conversions between values and registers
//!
//! # Architecture

//! # Example
//!
//! ```rust
//! use mabi_modbus::types::{RegisterConverter, WordOrder, RegisterDataType};
//!
//! // Create converter with Big Endian byte order
//! let converter = RegisterConverter::new(WordOrder::BigEndian);
//!
//! // Convert f32 to registers
//! let value: f32 = 123.456;
//! let registers = converter.f32_to_registers(value);
//! assert_eq!(registers.len(), 2);
//!
//! // Convert back to f32
//! let result = converter.registers_to_f32(&registers);
//! assert!((result - value).abs() < 0.001);
//!
//! // Use different word order (common in some PLC systems)
//! let swapped = RegisterConverter::new(WordOrder::BigEndianWordSwap);
//! let swapped_regs = swapped.f32_to_registers(value);
//! // Note: swapped_regs will have words in different order
//! ```
