Errors that may occur when applying the RandomProjectionCodec.

Variants

UnsupportedDtype(AnyArrayDType)

RandomProjectionCodec does not support the dtype

NonMatrixData

RandomProjectionCodec only supports matrix / 2d-shaped arrays

Fields

source: ShapeError

The source of the error

NonFiniteData

RandomProjectionCodec does not support non-finite (infinite or NaN) floating point data

NumberOfSamplesMismatch

RandomProjectionCodec cannot encode or decode from an array with $N$ samples to an array with a different number of samples

Fields

input: usize

Number of samples N in the input array

output: usize

Number of samples N in the output array

ProjectedArrayZeroComponents

RandomProjectionCodec cannot decode from an array with zero dimensionality $K$

CorruptedNumberOfComponents

RandomProjectionCodec cannot decode from an array with corrupted dimensionality metadata

NumberOfFeaturesMismatch

RandomProjectionCodec cannot decode into an array with $D$ features that differs from the $D$ stored in the encoded metadata

Fields

metadata: usize

Number of features $D$ in the encoded array metadata

output: usize

Number of features $D$ in the decoded output array

MismatchedDecodeIntoArray

RandomProjectionCodec cannot decode into the provided array

Fields

source: AnyArrayAssignError

The source of the error

Trait Implementations

impl Debug for RandomProjectionCodecError

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

Formats the value using the given formatter.

impl Display for RandomProjectionCodecError

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

Formats the value using the given formatter.

impl Error for RandomProjectionCodecError

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<AnyArrayAssignError> for RandomProjectionCodecError

fn from(source: AnyArrayAssignError) -> Self

Converts to this type from the input type.

impl From<ShapeError> for RandomProjectionCodecError

fn from(source: ShapeError) -> Self

Converts to this type from the input type.
