Struct Shape 

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

The shape of a Tensor. Note that the fastest-moving axis occupies the lowest shape index, which is opposite to that in torch.

Implementations

impl Shape

pub fn new(x: usize, y: usize, z: usize, w: usize) -> Self

Trait Implementations

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<'de> Deserialize<'de> for Shape

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Shape

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

Formats the value using the given formatter.

impl From<[usize; 4]> for Shape

fn from(value: [usize; 4]) -> Self

Converts to this type from the input type.

impl From<Shape> for [usize; 4]

fn from(value: Shape) -> Self

Converts to this type from the input type.

impl From<ShapedIndex> for Shape

fn from(value: ShapedIndex) -> Self

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 Index<usize> for Shape

type Output = usize

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Shape

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl IntoBytes for Shape

fn into_bytes(self) -> Vec<u8>

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.

impl PartialOrd for Shape

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Shape

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Shape

impl Eq for Shape
