Struct kn_graph::shape::Shape

pub struct Shape {
    pub dims: Vec<Size>,
}

A shape with each dimension corresponding to Size.

Use one of the constructor Shape::new, one of the utilities Shape::single, Shape::fixed, Shape::ones or the the shape! macro to conveniently construct one:

// these are all equivalent
shape![Size::BATCH, 16, 8, 8];
Shape::new(vec![Size::BATCH, 16.into(), 8.into(), 8.into()]);
Shape::new(vec![Size::BATCH, Size::fixed(16), Size::fixed(8), Size::fixed(8)]);

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a copy 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 Display for Shape

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

Formats the value using the given formatter.

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 = Size

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl PartialEq for Shape

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Shape
