Struct Selection 

pub struct Selection { /* private fields */ }

The result of running a univariate selector over a feature matrix: the per-feature scores and the boolean selection mask, aligned to column order.

The scores vector holds one value per feature column (a variance, or an ANOVA F-statistic), and mask[j] flags whether feature j was selected. The two vectors always share the feature count.

Implementations

impl Selection

pub fn scores(&self) -> &[f64]

The per-feature scores, in column order.

pub fn mask(&self) -> &[bool]

The per-feature selection mask, in column order (true = kept).

pub fn selected_count(&self) -> usize

The number of features selected.

pub fn selected_indices(&self) -> Vec<usize>

The zero-based indices of the selected features, in ascending column order.

Trait Implementations

impl Clone for Selection

fn clone(&self) -> Selection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selection

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

Formats the value using the given formatter.

impl PartialEq for Selection

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