Struct FileSubRequest 

pub struct FileSubRequest {
    pub reference_type: u8,
    pub file_number: u16,
    pub record_number: u16,
    pub record_length: u16,
}

A single file sub-request record (7 bytes on the wire).

Used inside both Read File Record and Write File Record requests.

Fields

reference_type: u8

Reference type — must be 6.

file_number: u16

File number.

record_number: u16

Starting record number within the file.

record_length: u16

Number of records to read/write.

Implementations

impl FileSubRequest

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

Decode a single sub-request from a 7-byte slice.

Errors

Returns DecodeError::Truncated if data is shorter than 7 bytes. Returns DecodeError::LengthMismatch if data has extra bytes. Returns DecodeError::InvalidReferenceType if the reference type is not 6. Returns DecodeError::FileRecordOutOfRange if file or record fields are outside the Modbus file-record model.

Trait Implementations

impl Clone for FileSubRequest

fn clone(&self) -> FileSubRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FileSubRequest

impl Debug for FileSubRequest

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

impl Eq for FileSubRequest

impl PartialEq for FileSubRequest

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