Struct socketcan_hal::CanFrame

#[repr(C)]
pub struct CanFrame { /* private fields */ }

CanFrame

Uses the same memory layout as the underlying kernel struct for performance reasons.

Implementations

impl CanFrame

pub fn init(
    id: u32,
    data: &[u8],
    rtr: bool,
    err: bool
) -> Result<CanFrame, ConstructionError>

pub fn err(&self) -> u32

Return the error message

pub fn is_error(&self) -> bool

Check if frame is an error message

pub fn error(&self) -> Result<CanError, CanErrorDecodingFailure>

Trait Implementations

impl Clone for CanFrame

fn clone(&self) -> CanFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanFrame

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

Formats the value using the given formatter.

impl Default for CanFrame

fn default() -> CanFrame

Returns the “default value” for a type.

impl Frame for CanFrame

fn new(id: impl Into<Id>, data: &[u8]) -> Option<Self>

Create a new frame

fn id(&self) -> Id

Return the actual CAN ID (without EFF/RTR/ERR flags)

fn is_extended(&self) -> bool

Check if frame uses 29 bit extended frame format

fn is_remote_frame(&self) -> bool

Check if frame is a remote transmission request

fn dlc(&self) -> usize

Data length

fn data(&self) -> &[u8]

A slice into the actual data. Slice will always be <= 8 bytes in length

fn new_remote(id: impl Into<Id>, dlc: usize) -> Option<Self>

Creates a new remote frame (RTR bit set).

fn is_standard(&self) -> bool

Returns true if this frame is a standard frame.

fn is_data_frame(&self) -> bool

Returns true if this frame is a data frame.

impl UpperHex for CanFrame

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

Formats the value using the given formatter.
