Variants

UnknownColumn(String)

Requested column is not available in the data view.

ColumnLength

A column returned by crate::DataView has a length different from crate::DataView::nrows.

Fields

name: String

Column name.

expected: usize

Expected number of rows.

actual: usize

Actual number of rows.

UnsupportedColumnType

Requested column type is not supported by this data view.

Fields

name: String

Column name.

requested: &'static str

Requested logical type.

NonFiniteValue

Numeric input contains a non-finite value.

Fields

name: String

Column name.

row: usize

Row index.

InvalidWeight

Observation weight is not finite or is negative.

Fields

name: String

Column name.

row: usize

Row index.

InvalidResponseDomain

Response value is outside the family domain.

Fields

name: String

Column name.

family: &'static str

Family name.

row: usize

Row index.

UnknownCategoryLevel

Prediction data contains a categorical level not seen during training.

Fields

name: String

Column name.

level: String

Unknown level.

row: usize

Row index.

MissingResponse

The model spec did not include a response column.

EmptyData

The data view has no rows.

DuplicateParameter(&'static str)

A model parameter was configured more than once.

Spline(SplineError)

Spline term construction failed.

Fourier(FourierError)

Fourier term construction failed.

Model(ModelError)

Compiled core model validation failed.

Trait Implementations

impl Clone for FormulaError

fn clone(&self) -> FormulaError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FormulaError

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

Formats the value using the given formatter.

impl Display for FormulaError

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

Formats the value using the given formatter.

impl Error for FormulaError

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<FourierError> for FormulaError

fn from(source: FourierError) -> Self

Converts to this type from the input type.

impl From<ModelError> for FormulaError

fn from(source: ModelError) -> Self

Converts to this type from the input type.

impl From<SplineError> for FormulaError

fn from(source: SplineError) -> Self

Converts to this type from the input type.

impl PartialEq for FormulaError

fn eq(&self, other: &FormulaError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
