}

Errors specific to the Feature Factory library.

Variants

IoError(Error)

Wraps underlying I/O errors.

DataFusionError(DataFusionError)

Wraps errors from DataFusion.

ArrowError(ArrowError)

Wraps errors from Arrow.

ParquetError(ParquetError)

Wraps errors from Parquet.

InvalidParameter(String)

Indicates that an invalid parameter was provided (e.g., unsupported value or incorrect data type).

UnsupportedFormat(String)

Indicates that the provided data format is unsupported (e.g., unknown file format).

NotImplemented(String)

Indicates a feature or functionality has not yet been implemented.

MissingColumn(String)

Indicates that the specified column does not exist in the DataFrame.

FitNotCalled

Indicates the transform method was called before calling fit for a stateful transformer.

Trait Implementations

impl Debug for FeatureFactoryError

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

Formats the value using the given formatter.

impl Display for FeatureFactoryError

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

Formats the value using the given formatter.

impl Error for FeatureFactoryError

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.
