Failure to create or read an animation decoder.

Variants

InputTooLarge

The input is larger than the configured byte limit.

Fields

actual: usize

Actual input length in bytes.

maximum: usize

Configured maximum input length in bytes.

NotAnimatedWebp

The input is a valid WebP image but does not contain animation data.

DecoderOptionsInitialization

libwebp could not initialize its decoder options.

DecoderCreation

libwebp could not create an animation decoder.

DecoderInfo

libwebp could not provide animation metadata.

InvalidAnimationInfo

The animation metadata could not be represented by this crate’s types.

FrameSizeOverflow

A canvas or frame size overflowed the host address space.

LimitExceeded

A configured resource limit was exceeded.

Fields

limit: &'static str

Name of the exceeded limit.

actual: u64

Observed value.

maximum: u64

Configured maximum value.

FrameDecode

libwebp failed to decode the next frame.

InvalidTimestamp

Frame timestamps were not monotonic or could not be accumulated.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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 PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
