The question is how much memory consumption will SMALL_SLICE cause in the following code? Will the compiler optimize out the unread part?

const ARRAY_100KB: [u8; 102400] = [0; 102400];
static SMALL_SLICE: &[u8] = ARRAY_100KB.split_at(5).0;

Google Gemini said 21 bytes in total, which combined by 16 byte(fat pointer) + 5 byte(underlying data), but I'm not sure.

BTW, is that a better way to get a range of elements of a slice in constant environment?
