An error that can occur in this crate.

Generally this error corresponds to problems with input data or fitting a regression model.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InconsistentSlopes(InconsistentSlopes)

Number of slopes and output names is inconsistent.

NoData

Cannot fit model without data.

NoFormula

Cannot fit model without formula.

InvalidFormula

Given formula is invalid.

ColumnNotInData(String)

Requested column is not in data. (Column given as String)

ModelColumnNotInData(String)

A column used in the model is misising from the provided data

RegressorRegressandDimensionMismatch(String)

Regressor and regressand dimensions do not match. (Column given as String)

RegressionDataError(String)

Error while processing the regression data. (Details given as String)

ModelFittingError(String)

Error while fitting the model. (Details given as String)

InconsistentVectors

The given vectors have inconsistent lengths

InconsistentRegressionModel

The RegressionModel internal state is inconsistent

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
