Struct Shape 

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

Tensor shape (list of dimensions).

Implementations

impl Shape

pub fn new(dims: impl IntoIterator<Item = Dim>) -> Self

Creates a new shape from dimensions.

pub fn from_static(dims: impl IntoIterator<Item = usize>) -> Self

Creates a shape from static dimensions.

pub fn scalar() -> Self

Creates a scalar shape (rank 0).

pub fn rank(&self) -> usize

Returns the rank (number of dimensions).

pub fn dims(&self) -> &[Dim]

Returns the dimensions.

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

Returns the total number of elements (if statically known).

pub fn is_scalar(&self) -> bool

Returns true if this is a scalar (rank 0).

pub fn is_static(&self) -> bool

Returns true if all dimensions are statically known.

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<'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 Eq for Shape

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.

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.
