Enum OnlineError 

pub enum OnlineError {
    DimensionMismatch {
        expected: usize,
        got: usize,
    },
    InvalidHyperparameter(String),
    NotFitted,
}

Errors that can arise in online learning routines.

Variants

DimensionMismatch

Feature dimensionality does not match model dimensionality.

Fields

expected: usize

got: usize

InvalidHyperparameter(String)

A hyperparameter has an invalid value.

NotFitted

Prediction attempted before the model has received any data.

Trait Implementations

impl Debug for OnlineError

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

Formats the value using the given formatter.

impl Display for OnlineError

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

Formats the value using the given formatter.

impl Error for OnlineError

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>)
