Macro extendr_api::prelude::array
source ยท macro_rules! array { ($([$([$($x:expr),* $(,)*]),+ $(,)*]),+ $(,)*) => { ... }; ($([$($x:expr),* $(,)*]),+ $(,)*) => { ... }; ($($x:expr),* $(,)*) => { ... }; }
Expand description
Create an Array
with one, two or
three dimensions.
use ndarray::array;
let a1 = array![1, 2, 3, 4];
let a2 = array![[1, 2],
[3, 4]];
let a3 = array![[[1, 2], [3, 4]],
[[5, 6], [7, 8]]];
assert_eq!(a1.shape(), &[4]);
assert_eq!(a2.shape(), &[2, 2]);
assert_eq!(a3.shape(), &[2, 2, 2]);
This macro uses vec![]
, and has the same ownership semantics;
elements are moved into the resulting Array
.
Use array![...].into_shared()
to create an ArcArray
.
