* Make RelSlice uncopyableD. Shah2021-01-271-1/+1

* nexus: Switch from RelPtr to RelSliceD. Shah2021-01-271-4/+4
| | | | | | | | | | This replaces RelPtrs and a separate length field with a Rust-style slice containing both a pointer and a length; with bounds checking always enforced. Thus iterating over these structures is both cleaner and safer. Signed-off-by: D. Shah <dave@ds0.me>
