Expand description

Forms a (possibly-wide) raw pointer from a data address and metadata.

This function is safe but the returned pointer is not necessarily safe to dereference. For slices, see the documentation of slice::from_raw_parts for safety requirements. For trait objects, the metadata must come from a pointer to the same underlying erased type.
