Struct Layout 

pub struct Layout {
    pub dims: Vec<usize>,
    pub padded: Vec<usize>,
    pub modes: Vec<usize>,
    pub strides: Vec<usize>,
    pub order: DigitOrder,
    pub pad: PadPolicy,
}

The tensorization of one grid.

Fields

dims: Vec<usize>

Original grid shape (row-major, last axis fastest).

padded: Vec<usize>

Padded grid shape.

modes: Vec<usize>

Tensor mode sizes, most significant first.

strides: Vec<usize>

For each tensor mode, the stride of that digit in the padded grid.

order: DigitOrder

Digit order used.

pad: PadPolicy

Padding policy used.

Implementations

impl Layout

pub fn new(dims: &[usize], order: DigitOrder, pad: PadPolicy) -> Self

Build the tensorization of a grid of shape dims.

pub fn len(&self) -> usize

Number of original cells.

pub fn is_empty(&self) -> bool

Whether the grid is empty (never, by construction).

pub fn tensor_len(&self) -> usize

Number of tensor entries (padded cells).

pub fn pad_grid(&self, data: &[f64]) -> Vec<f64>

Mirror-pad data (shape dims) to the padded grid.

pub fn to_tensor(&self, padded: &[f64]) -> Vec<f64>

Padded grid → tensor order (gather).

pub fn from_tensor(&self, tensor: &[f64]) -> Vec<f64>

Tensor order → original grid (scatter + crop).
