Struct EmptyArray 

pub struct EmptyArray { /* private fields */ }

An implementation of the Array trait without any data.

This only tracks the shape of the array.

Implementations

impl EmptyArray

pub fn new(shape: Vec<usize>) -> EmptyArray

Create a new EmptyArray with the given shape.

Trait Implementations

impl Array for EmptyArray

fn as_any(&self) -> &dyn Any

Get the array as a Any reference

fn as_any_mut(&mut self) -> &mut dyn Any

Get the array as a mutable Any reference

fn create(&self, shape: &[usize], _fill_value: MtsArray) -> Box<dyn Array>

Create a new array with the same array origin, data type, and device as the current one, but with the requested shape.

fn copy(&self, device: DLDevice) -> Box<dyn Array>

Make a copy of this array

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

Get the shape of the array. This can be empty if the array has no shape (e.g. a scalar).

fn reshape(&mut self, shape: &[usize])

Change the shape of the array to the given shape

fn swap_axes(&mut self, axis_1: usize, axis_2: usize)

Swap the axes axis_1 and axis_2 in this array

fn move_data(&mut self, _: &dyn Array, _: &[mts_data_movement_t])

Set entries in self taking data from the input array.

fn device(&self) -> DLDevice

Get the device where this array’s data resides.

fn dtype(&self) -> DLDataType

Get the data type of this array.

fn as_dlpack( &self, _device: DLDevice, _stream: Option<i64>, _max_version: DLPackVersion, ) -> Result<DLPackTensor, Error>

Convert the array to a DLPack tensor. The returned pointer is owned by the caller (and cleaned up via its deleter).

fn from_dlpack( &self, _dlpack_tensor: DLPackTensor, ) -> Result<Box<dyn Array>, Error>

Create a new array from a DLPack tensor, taking ownership of the tensor’s data.

impl Clone for EmptyArray

fn clone(&self) -> EmptyArray

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EmptyArray

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

Formats the value using the given formatter.
