`manual_memcpy` fix fixes rust-lang#8160 Ideally this would work with `VecDeque`, but the current interface is unsuitable for it. At a minimum something like `range_as_slices` would be needed. changelog: Don't lint `manual_memcpy` on `VecDeque` changelog: Suggest `copy_from_slice` for `manual_memcpy` when applicable
