Impl std::error::Error for CanError #36

Closed andresv closed 3 years ago

andresv commented 3 years ago

Implements std::error::Error for CanError.

This allows simple use of anyhow for error handling.

use anyhow::Result;

fn run() -> Result<()> {
   let mut socket_rx = CANSocket::open("vcan0")?
   ...
   let m = messages::SteeringLevers::try_from(p.as_slice())?;
   ...
}

I think I have seen "std " e.g. in bitvec.
