I tried this code:
#![feature(iter_array_chunks)]
fn main() {
let x = [1].into_iter().array_chunks::<2>();
let x = x.into_remainder();
assert!(x.is_some());
}I expected to see this happen:
There should be a remainder as 1 will not be yielded.
Instead, this happened:
Compiling playground v0.0.1 (/playground)

thread 'main' panicked at src/main.rs:7:5:
assertion failed: x.is_some()
If this is intended behavior, then it should probably be documented, as the current documentation of ArrayChunks::into_remainder states that it:
Returns an iterator over the remaining elements of the original iterator that are not going to be returned by this iterator. The returned iterator will yield at most N-1 elements.
