Enum TransportError 

#[non_exhaustive]
pub enum TransportError {
    InvalidConfiguration(String),
    InterfaceNotFound(String),
    PermissionDenied,
    Io(Error),
    SendBufferFull,
    FrameError(FrameError),
    FdFrameOnNonFdBus,

    },
    ExtendedIdNotSupported,
}

Errors returned by transport operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidConfiguration(String)

The requested transport setup is contradictory or unsupported.

InterfaceNotFound(String)

The named interface does not exist on this host.

PermissionDenied

The caller lacks permission to open or operate the socket (typically: missing CAP_NET_RAW).

Io(Error)

Generic IO error from the underlying syscall.

SendBufferFull

The kernel’s send buffer is full and remained full after the bounded retry budget was exhausted.

FrameError(FrameError)

A frame the codec produced was rejected before any IO was issued.

FdFrameOnNonFdBus

A CAN-FD frame was passed to a classical-only bus.

PayloadExceedsBusCapacity

The frame’s payload length exceeds the bus’s max payload length.

Fields

len: u8

Payload length the caller attempted to send.

max: u8

Bus’s max payload length.

ExtendedIdNotSupported

The transport cannot send 29-bit extended IDs.

Trait Implementations

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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.
