If g is a Vec, then .iter() returns a std::slice::Iter and .into_iter() returns a std::vec::IntoIter. It looks like slice::Iter is just the size of two pointers (as I'd expect), and clone just copies the same values, while vec::IntoIter has all the fields a Vec has, as well as 2 pointer for the range iterated over, and allocated on Clone.
