Struct Shape 

pub struct Shape(/* private fields */);

Implementations

impl Shape

pub fn new(dims: impl Into<Arc<[usize]>>) -> Self

pub fn size(&self) -> usize

pub fn try_size(&self) -> Option<usize>

Checked total element count. Returns None on overflow.

pub fn dimensions(&self) -> usize

pub fn contains_dim(&self, dim: usize) -> bool

pub fn dim_at(&self, index: usize) -> usize

pub fn rank(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_scalar(&self) -> bool

pub fn is_vector(&self) -> bool

pub fn is_matrix(&self) -> bool

pub fn is_tensor(&self) -> bool

pub fn is_square(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = &usize>

pub fn as_slice(&self) -> &[usize]

Trait Implementations

impl AsRef<[usize]> for Shape

fn as_ref(&self) -> &[usize]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.

impl Default for Shape

fn default() -> Shape

Returns the “default value” for a type.

impl From<&[usize]> for Shape

fn from(dims: &[usize]) -> Self

Converts to this type from the input type.

impl From<&Shape> for Shape

fn from(shape: &Shape) -> Self

Converts to this type from the input type.

impl From<&Shape> for Strides

fn from(shape: &Shape) -> Self

Converts to this type from the input type.

impl From<(usize, usize)> for Shape

fn from(value: (usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize)> for Shape

fn from(value: (usize, usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize, usize)> for Shape

fn from(value: (usize, usize, usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize, usize, usize)> for Shape

fn from(value: (usize, usize, usize, usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize, usize, usize, usize)> for Shape

fn from(value: (usize, usize, usize, usize, usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize, usize, usize, usize, usize)> for Shape

fn from(value: (usize, usize, usize, usize, usize, usize, usize)) -> Shape

Converts to this type from the input type.

impl From<(usize, usize, usize, usize, usize, usize, usize, usize)> for Shape

fn from( value: (usize, usize, usize, usize, usize, usize, usize, usize), ) -> Shape

Converts to this type from the input type.

impl From<Vec<i32>> for Shape

fn from(dims: Vec<i32>) -> Self

Converts to this type from the input type.

impl From<Vec<usize>> for Shape

fn from(dims: Vec<usize>) -> Self

Converts to this type from the input type.

impl From<usize> for Shape

fn from(value: usize) -> Shape

Converts to this type from the input type.

impl Hash for Shape

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Shape

fn eq(&self, other: &Shape) -> 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.
