        expected: usize,
        actual: usize,
    },
    LabelOutOfRange {
        label: usize,

    InvalidConfig(String),
}

Errors raised by the classification models.

Variants

DimensionMismatch

Feature vector length did not match the model’s configured dimension.

Fields

expected: usize

actual: usize

LabelOutOfRange

The requested class label is outside the configured range.

Fields

label: usize

n_classes: usize

NotReady

Model has not seen enough samples yet.

Fields

observed: usize

required: usize

InvalidConfig(String)

Configuration value out of range.

Trait Implementations

impl Debug for ClassificationError

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

Formats the value using the given formatter.

impl Display for ClassificationError

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

Formats the value using the given formatter.

impl Error for ClassificationError

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.
