Struct SubRequestParams 

pub struct SubRequestParams {
    pub file_number: u16,
    pub record_number: u16,
    pub record_length: u16,
    pub record_data: Option<Vec<u16, MAX_PDU_DATA_LEN>>,
}

Parameters for a single file record sub-request.

Fields

file_number: u16

The file number to be read/written (0x0001 to 0xFFFF). In Modbus, files are logical groupings of records.

record_number: u16

The starting record number within the file (0x0000 to 0x270F). Each record is typically 2 bytes (one 16-bit register).

record_length: u16

The length of the record in number of 16-bit registers. For Read (FC 0x14), this is the amount to retrieve. For Write (FC 0x15), this must match the length of record_data.

record_data: Option<Vec<u16, MAX_PDU_DATA_LEN>>

The actual register values to be written to the file. This field is Some for Write File Record (FC 0x15) and None for Read File Record (FC 0x14). The data is stored in a heapless::Vec to ensure no_std compatibility.

Trait Implementations

impl Clone for SubRequestParams

fn clone(&self) -> SubRequestParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubRequestParams

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

Formats the value using the given formatter.

impl PartialEq for SubRequestParams

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