pub struct SocketCanIsoTPChannel { /* private fields */ }

SocketCAN CAN channel

Trait Implementations

impl Debug for SocketCanIsoTPChannel

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

Formats the value using the given formatter.

impl Drop for SocketCanIsoTPChannel

fn drop(&mut self)

Executes the destructor for this type.

impl IsoTPChannel for SocketCanIsoTPChannel

fn set_iso_tp_cfg(&mut self, cfg: IsoTPSettings) -> ChannelResult<()>

Sets the ISO-TP specific configuration for the Channel

impl PayloadChannel for SocketCanIsoTPChannel

fn write_bytes( &mut self, addr: u32, ext_id: Option<u8>, buffer: &[u8], timeout_ms: u32 ) -> ChannelResult<()>

Writes bytes to socketcan socket.

NOTE: Due to how ISO-TP channeling on SocketCAN works, there is a limitation when sending on a different address to what was defined in Self::set_iso_tp_cfg. It should work for most alternate address messages (EG: Global tester present), but longer messages will fail.

If buffer is less than 7 bytes (With Standard ISO-TP addressing), or less than 6 bytes (With Extended ISO-TP addressing), this function will attempt to open a parallel socketCAN channel in order to send an ISO-TP single frame request on the alternate requested address.

If buffer is more than 7 bytes and you request on an alternate address, then this function will fail with ChannelError::UnsupportedRequest

fn open(&mut self) -> ChannelResult<()>

This function opens the interface. It is ONLY called after set_ids and any other configuration function

fn close(&mut self) -> ChannelResult<()>

Closes and destroys the channel

fn set_ids(&mut self, send: u32, recv: u32) -> ChannelResult<()>

Configures the diagnostic channel with specific IDs for configuring the diagnostic server

fn read_bytes(&mut self, timeout_ms: u32) -> ChannelResult<Vec<u8>>

Attempts to read bytes from the channel.

fn clear_rx_buffer(&mut self) -> ChannelResult<()>

Tells the channel to clear its Rx buffer. This means all pending messages to be read should be wiped from the devices queue, such that PayloadChannel::read_bytes does not read them

fn clear_tx_buffer(&mut self) -> ChannelResult<()>

Tells the channel to clear its Tx buffer. This means all messages that are queued to be sent to the ECU should be wiped.

fn read_write_bytes( &mut self, addr: u32, ext_id: Option<u8>, buffer: &[u8], write_timeout_ms: u32, read_timeout_ms: u32 ) -> ChannelResult<Vec<u8>>

Attempts to write bytes to the channel, then listen for the channels response
