Crate socketcan2

Expand description

SocketCAN support.

Features

Receive can frames
Accurate timestamps (timestamps also support multi threading in contrast to receiving the TIMESTAMP via an ioctl call, which does not support mt)
epoll-support (allows to wait on multiple CAN devices in the same thread)
Send CAN frames (not implemented yet)
Filter CAN frames (not implemented yet)

Usage example

#[cfg(test)]
fn on_recv(msg: &Box<Msg>, _user_data: &u64) {
  println!("timestamp: {:?}", msg.timestamp());
  print!("received CAN frame (id: {}): ", msg.can_id());
  for i in 0..msg.len() {
    print!("{} ", msg[i as usize]);
  }
  println!("");
}
 
#[cfg(test)]
mod tests {
  use super::*;
  #[test]
  fn it_works() {
    let can = Can::open("vcan0").unwrap();
    let mut cg = CanGroup::<u64>::new();
    cg.add(can, 0).unwrap();
    match cg.next(Duration::milliseconds(-1), on_recv) {
      Ok(no_timeout) => if !no_timeout { panic!("timeout"); },
      Err(_) => panic!("error"),
    }
  }
}
