Describes the Descriptor of a Tensor.

Required Methods

fn rank(&self) -> usize

Returns the rank of the Tensor.

The rank of the Tensor is the number of its dimensions.

fn size(&self) -> usize

Returns the summed up length of all dimensions of the Tensor.

A Tensor of rank 2 with the following dimesion specification [5, 5] would have a size of 25.

fn dims(&self) -> &Vec<usize>

Returns the dimensions of the Tensor.

To return the length of one dimensions of the Tensor, you would call tensor_desc.dims()[0] // e.g. 64

fn dims_i32(&self) -> Vec<i32>

Returns the dimensions of the Tensor as Vec.

Provided Methods

fn default_stride(&self) -> Vec<usize>

Returns the default stride for an Rust allocated Tensor.

A rank 2 Tensor with dimensions [a, b] has a default stride of [b, 1] A rank 3 Tensor with dimensions [a, b, c] has a default stride of [b * c, c, 1] A rank 4 Tensor with dimensions [a, b, c, d] has a default stride of [b * c * d, c * d, d, 1] and so on.

fn default_stride_i32(&self) -> Vec<i32>

Returns the default stride for a Rust allocated Tensor as i32.
