Summary
Zerocopy: Some Ref methods are unsound with some type parameters
Details

The Ref methods into_ref, into_mut, into_slice, and into_slice_mut are unsound and may allow safe code to exhibit undefined behavior when used with Ref<B, T> where B is cell::Ref or cell::RefMut. Note that these methods remain sound when used with B types other than cell::Ref or cell::RefMut.

See https://github.com/google/zerocopy/issues/716 for a more in-depth analysis.

The current plan is to yank the affected versions soon. See https://github.com/google/zerocopy/issues/679 for more detail.
