Function split_at

pub const fn split_at<T>(slice: &[T], at: usize) -> (&[T], &[T])

A const equivalent of <[T]>::split_at

If at > slice.len(), this returns a slice, empty slice pair.

Const stabilization

The analogous std function was const-stabilized in Rust 1.71.0.

Example

use konst::slice::split_at;

let arr = [3, 5, 8, 13, 21, 34];

assert_eq!(split_at(&arr, 0), (&[][..], &[3, 5, 8, 13, 21, 34][..]));

assert_eq!(split_at(&arr, 1), (&[3][..], &[5, 8, 13, 21, 34][..]));

assert_eq!(split_at(&arr, 2), (&[3, 5][..], &[8, 13, 21, 34][..]));

assert_eq!(split_at(&arr, 5), (&[3, 5, 8, 13, 21][..], &[34][..]));

assert_eq!(split_at(&arr, 6), (&[3, 5, 8, 13, 21, 34][..], &[][..]));

assert_eq!(split_at(&arr, 7), (&[3, 5, 8, 13, 21, 34][..], &[][..]));
