Crate arr_rs

arr-rs - implementation of multidimensional array in Rust

Examples

// import the crate
use arr_rs::prelude::*;

// create an array: (4 elements, 2 dimensions)
let arr = Array::<i32>::new(vec![1, 2, 3, 4], vec![2, 2]);

// create same array using macro:
let arr: Array::<i32> = array!([[1, 2], [3, 4]]);

// create random array with the same shape:
let arr = Array::<i32>::rand(vec![2, 2]);

// array supports display and pretty display
let arr: Array<f64> = array!([[1, 2, 3], [4, 5, 6], [7, 8, 9]]);
println!("{array}");
println!("{array:#}");

// perform some chained operations on array:
let res = arr
    .map(|item| item * 2)
    .filter(|item| item % 3 == 0)
    .ravel()
    .slice(0 .. 2);
