Function odds::slice::split_aligned_for

pub fn split_aligned_for<T: Pod>(data: &[u8]) -> (&[u8], &[T], &[u8])

Split the input slice into three chunks, so that the middle chunk is a slice of a larger "block size" (for example T could be u64) that is correctly aligned for T.

The first and last returned slices are the remaining head and tail parts that could not be baked into &[T]

Examples

extern crate odds;
use odds::slice::split_aligned_for;

fn count_ones(data: &[u8]) -> u32 {
    let mut total = 0;
    let (head, mid, tail) = split_aligned_for::<[u64; 2]>(data);
    total += head.iter().map(|x| x.count_ones()).sum();
    total += mid.iter().map(|x| x[0].count_ones() + x[1].count_ones()).sum();
    total += tail.iter().map(|x| x.count_ones()).sum();
    total
}

fn main() {
    assert_eq!(count_ones(&vec![3u8; 127]), 127 * 2);
}
