Errors raised while decoding DICOM bytes into voxels.

Variants

Dicom(DcmError)

The DICOM payload could not be parsed or decompressed.

Metadata(MetadataError)

Frame metadata could not be extracted.

UnsupportedSamplesPerPixel

The image uses an unsupported sample layout for volumetric decoding.

Fields

samples_per_pixel: u16

Unsupported sample count.

UnsupportedBitsAllocated

The image uses a pixel storage layout that is not yet supported.

Fields

bits_allocated: u16

Unsupported bit depth.

NativePixelLengthMismatch

The frame count does not match the available native bytes.

Fields

actual: usize

Raw pixel byte length found in the dataset.

frames: u32

Number of frames expected from metadata.

bytes_per_frame: usize

Bytes required per frame.

MissingPixelData

No pixel data element was present in the dataset.

PixelCountMismatch

The decoded pixel count does not match the frame dimensions.

Fields

frame_index: u32

Zero-based frame index.

expected: usize

Expected grayscale voxel count.

actual: usize

Actual number of decoded values.

ExpectedSingleFrame

A single-frame decode helper was used for a multi-frame payload.

Fields

actual_frames: usize

Number of decoded frames in the source object.

Trait Implementations

impl Debug for DicomDecodeError

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

Formats the value using the given formatter.

impl Display for DicomDecodeError

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

Formats the value using the given formatter.

impl Error for DicomDecodeError

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<DcmError> for DicomDecodeError

fn from(source: DcmError) -> Self

Converts to this type from the input type.

impl From<MetadataError> for DicomDecodeError

fn from(source: MetadataError) -> Self

Converts to this type from the input type.
