Variants

TransmitTimeout

TX timeout (by netdevice driver)

LostArbitration(u8)

Arbitration was lost. Contains the number after which arbitration was lost or 0 if unspecified

ControllerProblem(ControllerProblem)

Controller problem, see ControllerProblem

ProtocolViolation

Fields

vtype: ViolationType

location: Location

Protocol violation at the specified Location. See ProtocolViolation for details.

TransceiverError

Transceiver Error.

NoAck

No ACK received for current CAN frame.

BusOff

Bus off (due to too many detected errors)

BusError

Bus error (due to too many detected errors)

Restarted

The bus has been restarted

Unknown(u32)

Unknown, possibly invalid, error

Implementations

impl CanError

pub fn from_frame(frame: &CanFrame) -> Result<Self, CanErrorDecodingFailure>

Trait Implementations

impl Clone for CanError

fn clone(&self) -> CanError

Returns a copy 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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CanError

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

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error occurred.

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 provide(&'a self, req: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl Error for CanError

fn kind(&self) -> ErrorKind

Convert error to a generic CAN error kind
