Struct VecDataset 

pub struct VecDataset { /* private fields */ }

A simple in-memory dataset backed by a Vec<Sample>.

Useful for building datasets programmatically or loading from CSV/JSON.

Implementations

impl VecDataset

pub fn new(samples: Vec<Sample>, name: &str) -> Self

Create a VecDataset from a vector of samples.

Panics

Panics if samples is empty.

pub fn from_flat( features: &[f64], feature_shape: &[usize], targets: &[f64], target_shape: &[usize], name: &str, ) -> Self

Build from feature/target matrices.

features: [n_samples, n_features] row-major targets: [n_samples, n_targets] row-major

Trait Implementations
