Implementations§

impl Shape

pub fn num_elements(&self) -> usize

pub fn from_dims(dims: &[usize]) -> Shape

pub fn rank(&self) -> usize

The rank is the number of dimensions, 0 for a scalar value, 1 for a vector, etc.

pub fn into_dims(self) -> Vec<usize>

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

The dimensions as a slice of usize.

pub fn elem_count(&self) -> usize

The total number of elements, this is the product of all dimension sizes.

pub fn stride_contiguous(&self) -> Vec<usize>

The strides given in number of elements for a contiguous n-dimensional arrays using this shape.

pub fn is_contiguous(&self, stride: &[usize]) -> bool

Returns true if the strides are C contiguous (aka row major).

pub fn is_fortran_contiguous(&self, stride: &[usize]) -> bool

Returns true if the strides are Fortran contiguous (aka column major).

pub fn extend(self, additional_dims: &[usize]) -> Shape

Modifies the shape by adding a list of additional dimensions at the end of the existing dimensions.

pub fn broadcast_shape_binary_op( &self, rhs: &Shape, op: &'static str, ) -> Result<Shape, Error>

Check whether the two shapes are compatible for broadcast, and if it is the case return the broadcasted shape. This is to be used for binary pointwise ops.
