83 T must not be an opaque Rust type or opaque C++ type. Support for opaque Rust
88 Only rust::Slice\<const T\> is copy-assignable, not rust::Slice\<T\>. (Both are
89 move-assignable.) You'll need to write std::move occasionally as a reminder that
90 accidentally exposing overlapping &amp;mut \[T\] to Rust is UB.
