Struct ReadWriteMultipleRegistersRequest 

pub struct ReadWriteMultipleRegistersRequest<'buf> {
    pub read_address: Address,
    pub read_quantity: Quantity,

}

FC 0x17 — Read/Write Multiple Registers request.

Atomically reads read_quantity registers starting at read_address and writes write_quantity registers starting at write_address.

Fields

read_address: Address

Starting address for reading (0-indexed).

read_quantity: Quantity

Number of registers to read (1..=125).

write_address: Address

Starting address for writing (0-indexed).

write_quantity: Quantity

Number of registers to write (1..=121).

write_byte_count: u8

Number of bytes in the write data (should be write_quantity * 2).

write_register_values: &'buf [u8]

Register values to write in big-endian byte order.

Implementations

impl<'buf> ReadWriteMultipleRegistersRequest<'buf>

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

Decode from PDU data after the function code byte.

Errors

Returns DecodeError::Truncated if data is too short. Returns DecodeError::QuantityOutOfRange if either quantity is out of range. Returns DecodeError::ByteCountMismatch if the declared byte count does not match the remaining data length.

Trait Implementations

impl<'buf> Clone for ReadWriteMultipleRegistersRequest<'buf>

fn clone(&self) -> ReadWriteMultipleRegistersRequest<'buf>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'buf> Copy for ReadWriteMultipleRegistersRequest<'buf>

impl<'buf> Debug for ReadWriteMultipleRegistersRequest<'buf>

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

Formats the value using the given formatter.

impl Encode for ReadWriteMultipleRegistersRequest<'_>

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).

impl<'buf> Eq for ReadWriteMultipleRegistersRequest<'buf>

impl<'buf> PartialEq for ReadWriteMultipleRegistersRequest<'buf>

fn eq(&self, other: &ReadWriteMultipleRegistersRequest<'buf>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
