Is there a way to copy &[T] into &mut [MaybeUninit<T>] without unsafe?

[alice]

I'd like to point out that the copy itself can be written in safe code, since it appears that nobody has pointed it out yet.

fn copy_data<T: Copy>(from: &[T], to: &mut [MaybeUninit<T>]) {
    assert_eq!(from.len(), to.len());
    
    for (from, to) in from.iter().zip(to) {
        *to = MaybeUninit::new(*from);
    }
}
