Struct Batch 

pub struct Batch<'a> { /* private fields */ }

A contiguous dataset batch view.

inputs and targets are flat row-major buffers.

Implementations

impl<'a> Batch<'a>

pub fn len(&self) -> usize

Returns the number of samples in this batch.

pub fn is_empty(&self) -> bool

Returns true if this batch is empty.

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_flat(&self) -> &'a [f32]

Returns the contiguous flat inputs buffer.

Shape: (len * input_dim,).

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

Returns the contiguous flat targets buffer.

Shape: (len * target_dim,).

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

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

Panics if idx >= len.

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

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

Panics if idx >= len.

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

Performs copy-assignment from source.

impl<'a> Debug for Batch<'a>
