Function subarray 

pub fn subarray<const S: usize, T>(slice: &[T], index: usize) -> &[T; S]

Get a subarray of length S at index.

Safety

This function is safe if given a valid slice.

Examples

use ps_util::subarray;
let data = [1, 2, 3, 4, 5];
let chunk: &[i32; 2] = subarray::<2, i32>(&data, 1);
assert_eq!(chunk, &[2, 3]);

Works with vectors:

use ps_util::subarray;
let vec = vec!["a", "b", "c", "d"];
let chunk: &[&str; 3] = subarray::<3, &str>(&vec, 0);
assert_eq!(chunk, &["a", "b", "c"]);

Panics

Panics if index + S exceeds the slice length:

use ps_util::subarray;
let data = [1, 2, 3];
let _chunk: &[i32; 3] = subarray::<3, i32>(&data, 1);
