impl Ord for Id
Implement Ord
according to the CAN arbitration rules
When performing arbitration, frames are looked at bit for bit starting from the beginning. A bit with the value 0 is dominant and a bit with value of 1 is recessive.
When two devices are sending frames at the same time, as soon as the first bit is found which differs, the frame with the corresponding dominant 0 bit will win and get to send the rest of the frame.
This implementation of Ord
for Id
will take this into consideration
and when comparing two different instances of Id
the “smallest” will
always be the ID which would form the most dominant frame, all other
things being equal.
