Variants

Jpeg(JpegError)

JPEG parse or entropy decode failed.

Unsupported(&'static str)

Input is outside the currently implemented experimental slice.

Dct53(DctTransformError)

The 5/3 DCT-grid transform could not execute.

Dct97(DctTransformError)

The 9/7 DCT-grid transform could not execute.

Accelerator(TranscodeStageError)

Optional transform acceleration failed.

MemoryCapExceeded

The requested transcode workspace exceeds the shared process safety cap.

Fields

requested: usize

Requested host bytes.

cap: usize

Maximum permitted host bytes.

HostAllocationFailed

The host allocator could not reserve the requested transcode workspace.

Fields

bytes: usize

Requested host bytes.

Metrics(MetricsError)

Validation metric construction failed.

Validation(&'static str)

Validation encountered an out-of-range or non-finite coefficient.

InternalInvariant

Internal transcode or batch-scheduler state violated an invariant.

Fields

what: &'static str

Stable description of the violated invariant.

Encode(Htj2kEncodeError)

Native HTJ2K encode failed.

Trait Implementations

impl Debug for JpegToHtj2kError

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

Formats the value using the given formatter.

impl Display for JpegToHtj2kError

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

Formats the value using the given formatter.

impl Error for JpegToHtj2kError

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 JpegToHtj2kError

fn from(value: JpegError) -> Self

Converts to this type from the input type.
