There was a problem hiding this comment.
FYI you can sue a more idiomatic version:
pub fn u8_to_u64(input: &[u8], output: &mut [u64]) {
assert_eq!(input.len(), 8 * output.len());
input
.chunks_exact(8)
.map(|c| c.try_into().unwrap())
.map(u64::from_be_bytes)
.zip(output.iter_mut())
.for_each(|(inp, out)| *out = inp)
}And in future array_chunks can make it even nicer.
