Enum FeatureError 

pub enum FeatureError {
    MissingFeature(String),
    TypeMismatch {
        feature: String,
        expected: String,
        got: String,
    },
    InvalidTransform(String),
    EmptyInput,
}

Errors produced by the feature extraction pipeline.

Variants

MissingFeature(String)

A required feature was not found and no imputer was configured.

TypeMismatch

A transform received a value of the wrong type.

Fields

feature: String

expected: String

got: String

InvalidTransform(String)

The transform parameters are invalid (e.g., degree = 0).

EmptyInput

The input batch or data slice is empty.

Trait Implementations

impl Clone for FeatureError

fn clone(&self) -> FeatureError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureError

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

Formats the value using the given formatter.

impl Display for FeatureError

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

Formats the value using the given formatter.

impl Error for FeatureError

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 PartialEq for FeatureError

fn eq(&self, other: &FeatureError) -> 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.
