Enum DropStrategy 

#[non_exhaustive]
pub enum DropStrategy {
    None,
    First,
    IfBinary,
}

Strategy for dropping one-hot columns to avoid multicollinearity.

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.

None

Keep all categories (default).

First

Drop the first category from each feature.

IfBinary

Drop the first category only for binary (2-category) features.

Trait Implementations

impl Clone for DropStrategy

fn clone(&self) -> DropStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropStrategy

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

Formats the value using the given formatter.

impl Default for DropStrategy

fn default() -> DropStrategy

Returns the “default value” for a type.

impl PartialEq for DropStrategy

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