}

Errors that can occur during JPEG parsing or encoding.

Variants

UnexpectedEof

Input data is too short or truncated.

InvalidSoi

Missing SOI (0xFFD8) at start of data.

MissingEoi

Missing EOI (0xFFD9) — non-fatal for some files.

UnsupportedMarker(u8)

Encountered an unsupported JPEG marker (progressive, arithmetic, etc.).

InvalidMarkerData(&'static str)

A marker segment has invalid or inconsistent length/content.

HuffmanDecode

Huffman decode error (invalid code encountered in scan data).

InvalidQuantTableId(u8)

Quantization table ID out of range (0–3).

InvalidHuffmanTableId(u8)

Huffman table ID out of range or missing.

UnknownComponentId(u8)

Component ID referenced in SOS not found in SOF.

InvalidDimensions

Image dimensions or sampling factors are invalid.

UnsupportedPrecision(u8)

12-bit precision is not supported.

Trait Implementations

impl Clone for JpegError

fn clone(&self) -> JpegError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JpegError

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

Formats the value using the given formatter.

impl Display for JpegError

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

Formats the value using the given formatter.

impl Error for JpegError

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<JpegError> for StegoError

fn from(e: JpegError) -> Self

Converts to this type from the input type.

impl PartialEq for JpegError

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