Enum ShapeDim 

pub enum ShapeDim {
    Rank0(usize),
    Rank1(usize),
    Rank2 {
        rows: usize,
        cols: usize,
    },
    Rank3 {

    RankN(Vec<usize>),
    Dictionary {
        n_keys: usize,
        n_values: Vec<usize>,
    },
    Collection(Vec<ShapeDim>),
    Unknown,
}

Recursively-describable dimensional rank for any Value.

Variants

Rank0(usize)

Rank-0 - must always be 1

Rank1(usize)

Array row count

Rank2

Relational table with row/column counts.

Fields

rows: usize

cols: usize

Rank3

3d object

Fields

x: usize

y: usize

z: usize

Rank4

4d Object

Fields

a: usize

b: usize

c: usize

d: usize

RankN(Vec<usize>)

N-dimensional tensor.

Dictionary

Dictionary shape

Fields

n_keys: usize

n_values: Vec<usize>

Collection(Vec<ShapeDim>)

Heterogeneous ordered collection. Covers lists, tuples, cubes (with varying row-counts) and user-custom chunked types.

The order is significant; for tuples it is the fixed arity order.

Unknown

Shape could not be determined.

Trait Implementations

impl Clone for ShapeDim

fn clone(&self) -> ShapeDim

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeDim

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

Formats the value using the given formatter.

impl PartialEq for ShapeDim

fn eq(&self, other: &ShapeDim) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Shape for ShapeDim

Implement Shape for ShapeDim so recursive calls like item.shape_3d() compile when iterating Collection(Vec<ShapeDim>).

fn shape(&self) -> ShapeDim

Returns arbitrary Shape dimension for any data shape

fn shape_1d(&self) -> usize

Returns the first dimension shape

fn shape_2d(&self) -> (usize, usize)

Returns the first and second dimension shapes

fn shape_3d(&self) -> (usize, usize, usize)

Returns the first, second and third dimension shapes

fn shape_4d(&self) -> (usize, usize, usize, usize)

Returns the first, second, third and fourth dimension shapes

impl Eq for ShapeDim
