Struct ReadHoldingRegistersRequest 

pub struct ReadHoldingRegistersRequest {
    pub address: Address,
    pub quantity: Quantity,
}

FC 0x03 — Read Holding Registers request.

Reads 1..=125 contiguous holding registers starting at address.

Fields

address: Address

Starting address (0-indexed).

quantity: Quantity

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

Implementations

impl ReadHoldingRegistersRequest

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

Decode from PDU data after the function code byte.

Errors

Returns DecodeError::Truncated if data is shorter than 4 bytes. Returns DecodeError::LengthMismatch if data has extra bytes. Returns DecodeError::QuantityOutOfRange if the quantity is not in 1..=125.

Trait Implementations

impl Clone for ReadHoldingRegistersRequest

fn clone(&self) -> ReadHoldingRegistersRequest

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for ReadHoldingRegistersRequest

impl Debug for ReadHoldingRegistersRequest

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

Formats the value using the given formatter.

impl Encode for ReadHoldingRegistersRequest

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

impl Eq for ReadHoldingRegistersRequest

impl PartialEq for ReadHoldingRegistersRequest

fn eq(&self, other: &ReadHoldingRegistersRequest) -> 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.
