Function array_append::split

pub fn split<const N: usize, const M: usize, T>(
    a: [T; N]
) -> ([T; M], [T; N - M])

Splits the given array a at the given point M. Returns a tuple containing two arrays where the first element is an array containing all elements from a[..M] and the second element is an array containing all elements from a[M..]. No elements are dropped, copied or cloned.

Example

let arr = [1usize, 2, 3, 4, 5];

// Currently, the turbofish syntax is required. rustc still cannot infer
// them even if you fully annotate these variables' types.
let (left, right) = split::<5, 3, usize>(arr);

assert_eq!(left, [1, 2, 3]);
assert_eq!(right, [4, 5]);
