Struct metatensor::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.
