Enum CanError 

#[repr(u8)]
pub enum CanError {
    Bit = 1,
    Stuff = 2,
    Form = 3,
    Ack = 4,
    Crc = 5,
    Other = 6,
}

The error codes which can be delivered in a CAN frame

These are set by a receiver when it detects an error in a received frame, and received globally by all nodes on the bus

Variants

Bit = 1

The transmitter detected a different value on the bus than the value is was transmitting at a point in the message after the arbitration process (sending of the ID)

Stuff = 2

A receiver detected a sequence of 6 bits of the same level, indicating a failure in bit stuffing

Form = 3

A reveiver detected a malformed can frame (e.g. the SOF bit was not dominant, etc)

Ack = 4

The transmitter did not detect an ACK from any receivers

Crc = 5

A receiver detected a mismatch in CRC value for the message

Other = 6

There are other bit patterns possible for the error field, but they have no defined meaning

Implementations

impl CanError

pub fn from_raw(raw: u8) -> Self

Create a CanError from the on-bus error code

Trait Implementations

impl Clone for CanError

fn clone(&self) -> CanError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CanError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CanError

fn fmt(&self, __snafu_display_formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CanError

where Self: Debug + Display,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl ErrorCompat for CanError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
