Variants

BufferTooShort

The packet buffer is too short to contain the expected data.

Fields

expected: usize

actual: usize

InvalidField(String)

Invalid field value encountered during parsing.

UnsupportedLayer(String)

The layer type is not supported or recognized.

LayerNotFound(LayerKind)

Attempted to access a layer that doesn’t exist in the packet.

ChecksumMismatch

Checksum verification failed.

Fields

expected: u16

actual: u16

InvalidProtocol(u8)

Invalid protocol number.

ParseError

Failed to parse layer at the given offset.

Fields

offset: usize

message: String

Field access error.

BindingNotFound

Layer binding not found.

Fields

lower: LayerKind

upper: LayerKind

Neighbor resolution failed.

InvalidMac(String)

Invalid MAC address.

InvalidIp(String)

Invalid IP address.

NotSupported(String)

Operation not supported.

Timeout(u64)

Timeout error.

Io(String)

I/O error wrapper.

Implementations

impl PacketError

pub fn buffer_too_short(expected: usize, actual: usize) -> Self

Create a buffer too short error.

pub fn parse_error(offset: usize, message: impl Into<String>) -> Self

Create a parse error.

pub fn binding_not_found(lower: LayerKind, upper: LayerKind) -> Self

Create a binding not found error.

pub fn is_recoverable(&self) -> bool

Check if this is a recoverable error.

Trait Implementations

impl Debug for PacketError

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

Formats the value using the given formatter.

impl Display for PacketError

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

Formats the value using the given formatter.

impl Error for PacketError

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<Error> for PacketError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<FieldError> for PacketError

fn from(source: FieldError) -> Self

Converts to this type from the input type.

impl From<PacketError> for FlowError

fn from(source: PacketError) -> Self

Converts to this type from the input type.
