Struct socketcan_isotp::IsoTpSocket

pub struct IsoTpSocket { /* fields omitted */ }

An ISO-TP socketcan socket.

Will be closed upon deallocation. To close manually, use std::drop::Drop. Internally this is just a wrapped file-descriptor.

Methods

impl IsoTpSocket

pub fn open(ifname: &str, src: u32, dst: u32) -> Result<Self, Error>

Open a named CAN ISO-TP device.

Usually the more common case, opens a socket can device by name, such as "vcan0" or "socan0".

pub fn open_with_opts(
    ifname: &str,
    src: u32,
    dst: u32,
    isotp_options: Option<IsoTpOptions>,
    rx_flow_control_options: Option<FlowControlOptions>,
    link_layer_options: Option<LinkLayerOptions>
) -> Result<Self, Error>

Open a named CAN ISO-TP device, passing additional options.

Usually the more common case, opens a socket can device by name, such as "vcan0" or "socan0".

pub fn open_if(if_index: c_int, src: u32, dst: u32) -> Result<Self, Error>

Open CAN ISO-TP device device by interface number.

Opens a CAN device by kernel interface number.

pub fn open_if_with_opts(
    if_index: c_int,
    src: u32,
    dst: u32,
    isotp_options: Option<IsoTpOptions>,
    rx_flow_control_options: Option<FlowControlOptions>,
    link_layer_options: Option<LinkLayerOptions>
) -> Result<Self, Error>

Open CAN ISO-TP device device by interface number, passing additional options.

Opens a CAN device by kernel interface number.

pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>

Change socket to non-blocking mode

pub fn read(&mut self) -> Result<&[u8]>

Blocking read data

pub fn write(&self, buffer: &[u8]) -> Result<()>

Blocking write a slice of data
