Error produced by the SSDV FEC decoder.

This enum lists the errors that can be produced by Decoder.

Variants

EoiOnFecPacket

The EOI flag is set on a FEC packet.

DuplicatedEoi

The EOI flag is set on several different systematic packets.

NumSystematicMismatch

There are different FEC packets containing a different value in the number of systematic packets field.

UnknownNumSystematic

The number of systematic packets in the image could not be determined.

This happens if the last systematic packet (carrying the EOI flag) is missing and there are no FEC packets.

EoiFecMismatch

There is a mismatch between the packet ID of the packet carrying the EOI flag and the number of systematic packets field in the FEC packets.

NotEnoughInput

There are not enough input packets for decoding.

The decoder needs as least as many distinct input packets as systematic packets are there in the image.

OutputTooShort

The output buffer is too short.

The length of the output buffer must be greater or equal than the number of systematic packets in the image.

WrongSystematicId

A systematic packet has a wrong packet ID.

MultipleImageIds

There are multiple image IDs in the packets.

InconsistentFlags

There are different packets with inconsistent values of the flags field.

DimensionsMismatch

There are systematic packets with different values of the image width or height.

NoSystematic

There are no systematic packets.

At least one systematic packet is required to obtain the image width and height.

Trait Implementations

impl Clone for DecoderError

fn clone(&self) -> DecoderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecoderError

impl Debug for DecoderError

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

Formats the value using the given formatter.

impl Display for DecoderError

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

Formats the value using the given formatter.

impl Eq for DecoderError

impl Error for DecoderError

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 Hash for DecoderError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DecoderError

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