Enum MaxFeatures 

pub enum MaxFeatures {
    Sqrt,
    Log2,
    All,
    Fixed(usize),
    Fraction(f64),
}

Strategy for selecting the number of features considered at each split.

Variants

Sqrt

Use the square root of the total number of features (default for classifiers).

Log2

Use the log2 of the total number of features.

All

Use all features (default for regressors).

Fixed(usize)

Use a specific number of features.

Fraction(f64)

Use a fraction of the total number of features.

Trait Implementations

impl Clone for MaxFeatures

fn clone(&self) -> MaxFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaxFeatures

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MaxFeatures

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MaxFeatures

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

impl Serialize for MaxFeatures

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MaxFeatures

impl StructuralPartialEq for MaxFeatures
