There is copy_from_slice() to copy all elements of a slice into another slice, which panics if the two slices have different lengths. Is there a similar thing to copy an initialized slice (i.e. &[T]) into an uninitialized slice (i.e. &mut [MaybeUninit<T>])? In addition to copying the elements (and…

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

The actual copying is easy, but I don't know of a safe way to get a non-MaybeUninit slice of the copied data afterwards.
