Errors produced by scry-learn operations.

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.

EmptyDataset

The dataset contains no samples.

InvalidData(String)

The input data contains NaN, Inf, or other non-finite values.

InvalidColumn(String)

A referenced column does not exist.

ShapeMismatch

Feature matrix dimensions do not match what the model expects.

Fields

expected: usize

Expected number of features.

got: usize

Actual number of features provided.

NotFitted

predict() or transform() called before fit().

InvalidParameter(String)

An invalid hyperparameter was supplied.

ConvergenceFailure

No convergence within the iteration limit.

Fields

iterations: usize

Number of iterations attempted.

tolerance: f64

Convergence tolerance.

Io(Error)

I/O error during file operations.

Csv(String)

CSV parsing error.

InvalidFeatureIndex(usize)

A referenced feature index is out of bounds.

Trait Implementations

impl Debug for ScryLearnError

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

Formats the value using the given formatter.

impl Display for ScryLearnError

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

Formats the value using the given formatter.

impl Error for ScryLearnError

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<Error> for ScryLearnError

fn from(err: Error) -> Self

Converts to this type from the input type.
