Function std::ptr::from_raw_parts

pub fn from_raw_parts<T>(    data_address: *const (),     metadata: <T as Pointee>::Metadata) -> *const T where    T: ?Sized, 

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.
