Struct DiagnosticsRequest 

pub struct DiagnosticsRequest<'buf> {
    pub sub_function: DiagnosticSubFunction,
    pub data: &'buf [u8],
}

FC 0x08 — Diagnostics request.

The sub-function code selects the diagnostic action. Diagnostic data is encoded as N x 2 bytes per Spec V1.1b3 §6.8.

Fields

sub_function: DiagnosticSubFunction

Diagnostic sub-function code.

data: &'buf [u8]

Sub-function data (typically 2 bytes, but variable for Return Query Data).

Implementations

impl<'buf> DiagnosticsRequest<'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 shorter than 2 bytes. Returns DecodeError::UnknownFunctionCode if the sub-function code is not recognized (reused as a general “unknown sub-code” error via the raw value). Returns DecodeError::InvalidDiagnosticDataLength if the payload is not an even number of bytes.

Trait Implementations

impl<'buf> Clone for DiagnosticsRequest<'buf>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'buf> Copy for DiagnosticsRequest<'buf>

impl<'buf> Debug for DiagnosticsRequest<'buf>

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

Formats the value using the given formatter.

impl Encode for DiagnosticsRequest<'_>

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 DiagnosticsRequest<'buf>

impl<'buf> PartialEq for DiagnosticsRequest<'buf>

fn eq(&self, other: &DiagnosticsRequest<'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.
