Enum Error 

#[non_exhaustive]
pub enum Error {
    Io(ErrorKind),
    Incomplete(Incomplete),
    Trailing(TrailingBytes),
    InsufficientBuffer(InsufficientBuffer),
    InvalidProtocolVersion(u8),
    InvalidMessageTypeField(u8),
    InvalidReturnCode(u8),
    InvalidLength(u32),
    UnsupportedMessageID(MessageId),
    Sd(Error),
}

Errors that can occur when encoding, decoding, or validating SOME/IP messages.

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.

Io(ErrorKind)

An I/O error occurred while reading or writing bytes.

Incomplete(Incomplete)

Input ended before the expected number of bytes could be read.

Trailing(TrailingBytes)

Bytes remained after a value that should have consumed the whole buffer.

InsufficientBuffer(InsufficientBuffer)

An output slice was too small for the bytes an encode needed to write.

InvalidProtocolVersion(u8)

The protocol version field contains an unsupported value.

InvalidMessageTypeField(u8)

The message type field contains an unrecognized value.

InvalidReturnCode(u8)

The return code field contains an unrecognized value.

InvalidLength(u32)

The SOME/IP length field was smaller than the 8-byte minimum (request_id..return_code).

UnsupportedMessageID(MessageId)

The message ID is not supported by the payload implementation.

Sd(Error)

A service discovery (SD) error occurred.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<EncodeToSliceError<Error>> for Error

fn from(e: EncodeToSliceError<Error>) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Bridges crate::e2e::Error onto protocol::Error so E2E failures can be reported through the same error type as the rest of the wire path.

E2E deliberately does not implement Encode/Decode (see the src/e2e module docs), so it keeps its own Error type. This impl only aligns the shape of that error with protocol::Error for callers that want a single error type to propagate; it does not change E2E’s protect/check behavior or on-wire bytes.

Mapping

e2e::Error currently has exactly one variant:

• crate::e2e::Error::BufferTooSmall { needed, actual } → maps to Error::InsufficientBuffer, not Error::Incomplete. Although Incomplete { needed, available } has the identical field shape, its semantics are decode-direction (“input ended before enough bytes could be read”). BufferTooSmall instead means an output slice was too small to hold the bytes E2E protect needed to write — the same direction as automotive_wire_codec::InsufficientBuffer (“An output slice was too small for the bytes an encode needed to write”). That is the semantically correct counterpart, so needed/actual map directly onto InsufficientBuffer’s needed/available fields.

impl From<InsufficientBuffer> for Error

fn from(source: InsufficientBuffer) -> Self
