Defines the error codes received from the CAN peripheral

Variants

ArbitrationLost

The previous transmission failed due to an arbitration lost

Transmission

The previous transmission failed

Warning

The internal Transmit Error Counter or the internal Receive Error Counter is greater than 96 and the passive error state is entered.

Passive

The internal Transmit Error Counter or the internal Receive Error Counter is greater than 127 and the passive error state is entered.

BusOff

The internal Transmit Error Counter is greater than 255 and the bus-off state is entered.

Stuff

6 consecutive bits of equal value are detected on the bus. (When transmitting device detects 5 consecutive bits of equal value on the bus, it inserts a complemented one).

Form

The form of the received or the transmitted frame is different than the standard format.

Ack

There are no receivers on the bus or the sender caused an error.

BitRecessive

While transmitting a recessive bit, the receiver sensed a dominant bit.

BitDominant

While transmitting a dominant bit, the receiver sensed a recessive bit.

Crc

The frame has been corrupted on the CAN bus

SetBySoftware

Set by software to force the hardware to indicate the current communication status.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl From<Error> for ErrorCode

fn from(val: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error
