Crate divide_slice 

Divide slices into portions of same size

Divide_slice provides two additional methods to the primitive type slice:

• divide: divide a slice into n non-overlapping portions, returning an iterator.
• divide_mut: divide a slice into n mutable non-overlapping portions, returning an iterator.

Difference with slice::chunks

The standard library provides the methods chunks and chunks_mut, which return a (mutable) iterator over a given number of elements of a slice at the same time.

The difference between chunks and divide is that you determine the size of the chunks with chunks, and the number of subslices you want with divide:

use divide_slice::Divide;

let slice = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

let mut iter = slice.chunks(3);
assert_eq!(iter.next(), Some(&[1, 2, 3][..]));
assert_eq!(iter.next(), Some(&[4, 5, 6][..]));
assert_eq!(iter.next(), Some(&[7, 8, 9][..]));
assert_eq!(iter.next(), Some(&[10][..]));
assert_eq!(iter.next(), None);

let mut iter = slice.divide(4);
assert_eq!(iter.next(), Some(&[1, 2, 3][..]));
assert_eq!(iter.next(), Some(&[4, 5, 6][..]));
assert_eq!(iter.next(), Some(&[7, 8][..]));
assert_eq!(iter.next(), Some(&[9, 10][..]));
assert_eq!(iter.next(), None);

Divide is more appropriate when you want to split the work equally among different threads.

Structs

Portion

An iterator over a slice in n non-overlapping portions, starting at the beginning of the slice.

PortionMut

An iterator over a slice in n mutable non-overlapping portions, starting at the beginning of the slice.
