This would then lead to undefined behavior. - -### Example -``` -unsafe fn swap(x: &[*mut u32], y: &[*mut u32]) { - for (&x, &y) in x.iter().zip(y) { - core::mem::swap(&mut *x, &mut *y); - } -} -``` -Use instead: -``` -unsafe fn swap(x: &[*mut u32], y: &[*mut u32]) { - for (&x, &y) in x.iter().zip(y) { - core::ptr::swap(x, y); - } -} -```
