}A socket for a CAN device.
Will be closed upon deallocation. To close manually, use std::drop::Drop. Internally this is just a wrapped file-descriptor.
Methods
impl CANSocket[src]
fn open(ifname: &str) -> Result<CANSocket, CANSocketOpenError>
Open a named CAN device.
Usually the more common case, opens a socket can device by name, such as "vcan0" or "socan0".
fn open_if(if_index: c_uint) -> Result<CANSocket, CANSocketOpenError>
Open CAN device by interface number.
Opens a CAN device by kernel interface number.
fn set_read_timeout(&self, duration: Duration) -> Result<()>
Sets the read timeout on the socket
For convenience, the result value can be checked using
ShouldRetry::should_retry when a timeout is set.
fn set_write_timeout(&self, duration: Duration) -> Result<()>
Sets the write timeout on the socket
fn read_frame(&self) -> Result<CANFrame>
Blocking read a single can frame.
fn write_frame(&self, frame: &CANFrame) -> Result<()>
Blocking write a single can frame.
