Error returned while parsing, decrypting, or assembling WFB packets.

Variants

Empty

Packet buffer is empty.

TooLong

Packet exceeds WFB forwarder size.

ShortDataPacket

Data packet is too short.

ShortSessionPacket

Session packet is too short.

InvalidKeypair

WFB keypair is not the expected 64-byte file shape.

SessionEncryptFailed

Session-key encryption failed.

SessionDecryptFailed

Session-key decryption failed.

DataEncryptFailed

Data encryption failed.

DataDecryptFailed

Data decryption failed.

SessionEpochTooOld

Session epoch was older than the configured minimum.

Fields

session_epoch: u64

Epoch from the received session packet.

minimum_epoch: u64

Minimum epoch accepted by the receiver.

SessionChannelMismatch

Session packet was for a different WFB channel.

Fields

expected: u32

Expected channel id.

actual: u32

Actual channel id in the session packet.

UnsupportedFecType(u8)

FEC type is not the supported VDM Reed-Solomon mode.

UnknownPacketType(u8)

Forwarder packet type is unknown.

InvalidFecParameters

FEC parameters are invalid.

InvalidFragmentIndex

Fragment index is outside the current FEC block.

BlockIndexOverflow

Data nonce encoded a block index beyond the supported range.

InvalidPlainPacket

Decrypted plain packet is malformed.

PayloadTooLarge

Plain payload exceeds the WFB maximum.

MissingSession

Encrypted data packet arrived before a session key.

FecRecoveryFailed

FEC recovery failed.

Trait Implementations

impl Clone for WfbError

fn clone(&self) -> WfbError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WfbError

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

Formats the value using the given formatter.

impl Display for WfbError

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

Formats the value using the given formatter.

impl Eq for WfbError

impl Error for WfbError

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<WfbError> for PayloadRouteError

fn from(err: WfbError) -> Self

Converts to this type from the input type.

impl PartialEq for WfbError

fn eq(&self, other: &WfbError) -> 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.
