Function konst::slice::get_from

source · 
pub const fn get_from<T>(slice: &[T], start: usize) -> Option<&[T]>
Expand description

A const equivalent of slice.get(start..).

§Example

use konst::slice;

const FIBB: &[u16] = &[3, 5, 8, 13, 21, 34, 55, 89];

const TWO: Option<&[u16]> = slice::get_from(FIBB, 2);
const FOUR: Option<&[u16]> = slice::get_from(FIBB, 4);
const ALL: Option<&[u16]> = slice::get_from(FIBB, 0);
const NONE: Option<&[u16]> = slice::get_from(FIBB, 1000);

assert_eq!(TWO, Some(&[8, 13, 21, 34, 55, 89][..]));
assert_eq!(FOUR, Some(&[21, 34, 55, 89][..]));
assert_eq!(ALL, Some(FIBB));
assert_eq!(NONE, None);
