Enum UnknownStrategy 

#[non_exhaustive]
pub enum UnknownStrategy {
    Error,
    Ignore,
}

Strategy for handling categories seen at transform time but not at fit time.

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.

Error

Raise an error (default).

Ignore

Encode as all-zeros row.

Trait Implementations

impl Clone for UnknownStrategy

fn clone(&self) -> UnknownStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownStrategy

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

Formats the value using the given formatter.

impl Default for UnknownStrategy

fn default() -> UnknownStrategy

Returns the “default value” for a type.

impl PartialEq for UnknownStrategy

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