Enum CanError 

pub enum CanError {
    DataTooLong,
    InvalidFdLength,
}

What can go wrong building a CAN frame.

Variants

DataTooLong

The data is longer than the frame kind allows (8 bytes for classic CAN, 64 for CAN-FD).

InvalidFdLength

The data length is not one a CAN-FD frame can carry. CAN-FD allows 0 to 8 bytes, then only 12, 16, 20, 24, 32, 48, and 64.

Trait Implementations

impl Eq for CanError

impl Error for CanError

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

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

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>(&'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 PartialEq for CanError

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

Equality operator ==.

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

Inequality operator !=.
