Enum SplitterError 

pub enum SplitterError {
    InvalidFeatureIndex {
        index: usize,
        max: usize,
    },
    InsufficientSamples {
        samples: usize,
        min: usize,
    },
    NoValidSplits {
        feature: usize,
    },
    DataError(DataError),
    EmptySamples,
}

Split finding Errors that can occur during split finding.

These errors cover invalid inputs, insufficient samples, and data integrity issues that prevent finding valid splits.

Variants

InvalidFeatureIndex

Requested feature index is out of bounds.

Fields

index: usize

max: usize

InsufficientSamples

Too few samples to perform a split meeting minimum leaf size requirements.

Fields

samples: usize

min: usize

NoValidSplits

A feature had no valid split points (e.g., all values identical).

Fields

feature: usize

DataError(DataError)

Underlying data access error from feature matrix.

EmptySamples

Sample array is empty after filtering.

Trait Implementations

impl Debug for SplitterError

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

Formats the value using the given formatter.

impl Display for SplitterError

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

Formats the value using the given formatter.

impl Error for SplitterError

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<DataError> for SplitterError

fn from(source: DataError) -> Self

Converts to this type from the input type.

impl From<SplitterError> for TreeError

fn from(source: SplitterError) -> Self

Converts to this type from the input type.
