Struct FeatureMatrix 

pub struct FeatureMatrix<T, const N_FEATURES: usize> { /* private fields */ }

Type-safe feature matrix with compile-time feature count validation

Implementations

impl<T, const N_FEATURES: usize> FeatureMatrix<T, N_FEATURES>

where T: Clone + Default,

pub fn new(data: Array2<T>) -> Result<Self>

Create a new feature matrix with compile-time feature count validation

pub unsafe fn new_unchecked(data: Array2<T>) -> Self

Create a new feature matrix without validation (unsafe)

Safety

The caller must ensure that data.ncols() == N_FEATURES

pub fn n_samples(&self) -> usize

Get the number of samples

pub const fn n_features(&self) -> usize

Get the number of features (always N_FEATURES)

pub fn view(&self) -> ArrayView2<'_, T>

Get a view of the underlying data

pub fn feature(&self, index: FeatureIndex<N_FEATURES>) -> ArrayView1<'_, T>

Get a feature column by type-safe index

pub fn select_features<const N_SELECTED: usize>( &self, mask: &FeatureMask<N_FEATURES>, ) -> Result<FeatureMatrix<T, N_SELECTED>>

Select features using a type-safe mask

pub fn to_dynamic(self) -> DynamicFeatureMatrix<T>

Convert to a dynamic feature matrix

Trait Implementations

impl<T: Clone, const N_FEATURES: usize> Clone for FeatureMatrix<T, N_FEATURES>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, const N_FEATURES: usize> Debug for FeatureMatrix<T, N_FEATURES>

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

Formats the value using the given formatter.
