const-chunks

This crate provides a #![no_std]-compatible extension trait that lets you chunk iterators into constant-length arrays using const generics.

See the docs for more info.

use const_chunks::IteratorConstChunks;

let mut iter = vec![1, 2, 3, 4, 5].into_iter().const_chunks::<2>();
assert_eq!(iter.next(), Some([1,2]));
assert_eq!(iter.next(), Some([3,4]));
assert_eq!(iter.next(), None);

let mut remainder = iter.into_remainder().unwrap();
assert_eq!(remainder.next(), Some(5));
assert_eq!(remainder.next(), None);

Safety

This crate uses unsafe to manipulate uninitialized memory.

To prevent undefined behaviour, the code runs MIRI in CI, and is both very short and easy to audit.

Nevertheless, you should still consider this fact if you're trying to minimize unsafe dependencies.

MSRV

This crate requires rustc version 1.65 or newer.

This crate's MSRV is enforced through the manifest's rust-version key.
