ModbusDecoder

oxirs_modbus::codec::data_decoder

Struct ModbusDecoder 

Source 
pub struct ModbusDecoder;
Expand description

Stateless decoder for Modbus register arrays.

All methods are pure functions – no mutable state is held. Create one instance and reuse it freely.

Implementations§

Source§

impl ModbusDecoder

Source

pub fn decode( regs: &[u16], data_type: DecoderDataType, byte_order: ByteOrder, ) -> ModbusResult<ModbusTypedValue>

Decode a slice of raw u16 Modbus registers into a typed value.

§Arguments
  • regs - Slice starting at the register of interest. Must contain at least data_type.register_count() elements.
  • data_type - How to interpret the raw register data.
  • byte_order - Word and byte ordering used by the target device.
§Errors

Returns ModbusError when the slice is too short or the decoded floating-point value is non-finite (NaN / infinity).

Source

pub fn scale( value: &ModbusTypedValue, scale_factor: f64, offset: f64, ) -> Option<f64>

Apply scale factor and offset to a decoded value, producing an f64.

Returns None for string values.
