Struct Dataset 

pub struct Dataset { /* private fields */ }

A supervised dataset: inputs (X) and targets (Y).

Stored as contiguous buffers with row-major layout:

• inputs.len() == len * input_dim
• targets.len() == len * target_dim

Implementations

impl Dataset

pub fn from_flat( inputs: Vec<f32>, targets: Vec<f32>, input_dim: usize, target_dim: usize, ) -> Result<Self>

Build a dataset from flat buffers.

inputs is (len, input_dim) and targets is (len, target_dim).

pub fn from_rows(inputs: &[Vec<f32>], targets: &[Vec<f32>]) -> Result<Self>

Build a dataset from per-sample rows.

This is a convenience constructor (it copies into contiguous storage).

pub fn len(&self) -> usize

Returns the number of samples.

pub fn is_empty(&self) -> bool

Returns true if there are no samples.

pub fn input_dim(&self) -> usize

Returns the per-sample input dimension.

pub fn target_dim(&self) -> usize

Returns the per-sample target dimension.

pub fn inputs(&self) -> &Inputs

Returns a view of the inputs (X).

pub fn inputs_flat(&self) -> &[f32]

Returns the underlying contiguous inputs buffer.

Shape: (len * input_dim,).

pub fn targets_flat(&self) -> &[f32]

Returns the underlying contiguous targets buffer.

Shape: (len * target_dim,).

pub fn input(&self, idx: usize) -> &[f32]

Returns the idx-th input row (shape: (input_dim,)).

Panics if idx >= len.

pub fn target(&self, idx: usize) -> &[f32]

Returns the idx-th target row (shape: (target_dim,)).

Panics if idx >= len.

pub fn batch(&self, start: usize, len: usize) -> Batch<'_>

Returns a contiguous batch view.

Panics if the requested range is out of bounds.

pub fn batches(&self, batch_size: usize) -> Batches<'_>

Iterate contiguous batch views.

Panics if batch_size == 0.

Trait Implementations

impl Clone for Dataset

fn clone(&self) -> Dataset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dataset

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

Formats the value using the given formatter.
