Struct ReadInputRegistersResponse 

pub struct ReadInputRegistersResponse<'buf> {
    pub byte_count: u8,
    pub register_data: &'buf [u8],
}

Response to a Read Input Registers request (FC 0x04).

Fields

byte_count: u8

Number of data bytes that follow (should be 2 * register count).

register_data: &'buf [u8]

Raw register data in big-endian byte order.

Implementations

impl<'buf> ReadInputRegistersResponse<'buf>

pub fn count(&self) -> usize

Returns the number of registers in this response.

pub fn register(&self, index: usize) -> u16

Returns the register value at the given zero-based index.

Panics

Panics if index is out of range.

pub fn registers(&self) -> impl Iterator<Item = u16> + '_

Returns an iterator over all register values.

pub fn raw(&self) -> &'buf [u8]

Returns the raw register data bytes.

pub fn decode(data: &'buf [u8]) -> Result<Self, DecodeError>

Decode from the data bytes following the function code.

Errors

Returns DecodeError::Truncated if data is too short. Returns DecodeError::ByteCountMismatch if the declared byte count does not match the remaining data length.

Trait Implementations

impl<'buf> Debug for ReadInputRegistersResponse<'buf>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for ReadInputRegistersResponse<'_>

fn encode_into(&self, buf: &mut [u8]) -> Result<usize, EncodeError>

Write the full PDU (function code + data) into buf.

fn encoded_len(&self) -> usize

Total encoded length in bytes (including the function code byte).
