Errors that can arise when creating a codebook from a CSV file

Variants

Io(Error)

BlankColumn

Fields

col_name: String

A column had no values in it.

UnableToInferColumnType

Fields

col_name: String

Could not infer the data type of a column

UnsupportedDataType

Fields

col_name: String

dtype: DataType

Dataset contains a Arrow datatype that cannot currently be converted to a column metadata

CategoricalOverflow

Fields

col_name: String

Too many distinct values for categorical column. A category is represented by a u8, so there can only be 256 distinct values.

ColumnMetadata(ColMetadataListError)

The column with name appears more than once

RowNames(RowNameListError)

The column with name appears more than once

Polars(PolarsError)

Polars error

NoIdColumn

The user did not provide an index/ID column

NullValuesInIndex

There are null values in the index/ID column

SingleValueColumn(String)

There the column contains only a single unique value, which can cause zero-variance issues which in turn cause other numerical issues.

MultipleIdColumns

There is more than one column named some form of ID. For example, there is a column named ID and id.

Read(ReadError)

Problem reading data into a DataFrame

Trait Implementations

impl Debug for CodebookError

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

Formats the value using the given formatter.

impl Display for CodebookError

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

Formats the value using the given formatter.

impl Error for CodebookError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
