#81513)Expand description
Forms a (possibly-wide) raw pointer from a data pointer 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.
