Struct SocketCanChannel 

pub struct SocketCanChannel { /* private fields */ }

A CAN channel backed by a Linux SocketCAN FD socket.

Implements Transmit, Receive, TransmitFd, ReceiveFd, and Filterable.

Created via SocketCanDriver or SocketCanChannel::open.

Implementations

impl SocketCanChannel

pub fn open(ifname: &str) -> Result<Self, SocketCanError>

Open a channel on the named interface (e.g., "vcan0", "can0").

pub fn open_iface(ifindex: u32) -> Result<Self, SocketCanError>

Open a channel by kernel interface index.

Trait Implementations

impl Filterable for SocketCanChannel

type Error = SocketCanError

fn set_filters(&mut self, filters: &[Filter]) -> Result<(), Self::Error>

Apply the given set of acceptance filters.

fn clear_filters(&mut self) -> Result<(), Self::Error>

Remove all acceptance filters (accept everything).

impl Receive for SocketCanChannel

type Error = SocketCanError

type Timestamp = Instant

The timestamp type used by this backend (e.g., std::time::Instant).

fn receive(&mut self) -> Result<Timestamped<CanFrame, Instant>, Self::Error>

Blocks until a classic CAN frame is available.

fn try_receive( &mut self, ) -> Result<Option<Timestamped<CanFrame, Instant>>, Self::Error>

Returns immediately with Ok(None) if no frame is available.

fn receive_timeout( &mut self, timeout: Duration, ) -> Result<Option<Timestamped<CanFrame, Instant>>, Self::Error>

Blocks until a frame is available or the timeout expires. Returns Ok(None) on timeout.

impl ReceiveFd for SocketCanChannel

type Error = SocketCanError

type Timestamp = Instant

The timestamp type used by this backend (e.g., std::time::Instant).

fn receive_fd(&mut self) -> Result<Timestamped<Frame, Instant>, Self::Error>

Blocks until any frame is available; returns Frame enum.

fn try_receive_fd( &mut self, ) -> Result<Option<Timestamped<Frame, Instant>>, Self::Error>

Non-blocking variant.

fn receive_fd_timeout( &mut self, timeout: Duration, ) -> Result<Option<Timestamped<Frame, Instant>>, Self::Error>

Blocks until a frame is available or the timeout expires. Returns Ok(None) on timeout.

impl Transmit for SocketCanChannel

type Error = SocketCanError

fn transmit(&mut self, frame: &CanFrame) -> Result<(), Self::Error>

Send a classic CAN frame.

impl TransmitFd for SocketCanChannel

type Error = SocketCanError

fn transmit_fd(&mut self, frame: &CanFdFrame) -> Result<(), Self::Error>

Send a CAN FD frame.
