Variants

InvalidMagic

Fields

magic: u32

Leading 4 magic bytes don’t match when decoding

InvalidChannels

Fields

channels: u8

Invalid number of channels: expected 3 or 4

InvalidColorSpace

Fields

colorspace: u8

Invalid color space: expected 0 or 1

InvalidImageDimensions

Fields

width: u32

height: u32

Invalid image dimensions: can’t be empty or larger than 400Mp

InvalidImageLength

Fields

size: usize

width: u32

height: u32

Image dimensions are inconsistent with image buffer length

OutputBufferTooSmall

Fields

size: usize

required: usize

Output buffer is too small to fit encoded/decoded image

UnexpectedBufferEnd

Input buffer ended unexpectedly before decoding was finished

InvalidPadding

Invalid stream end marker encountered when decoding

IoError(Error)

Tuple Fields

0: Error

Generic I/O error from the wrapped reader/writer

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for Error

fn from(err: Error) -> Self

Performs the conversion.

impl From<Infallible> for Error

fn from(_: Infallible) -> Self

Performs the conversion.
