Function hurray_item_destroy 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn hurray_item_destroy(
    handle: *mut *mut HurrayItem,
) -> HurrayStatus

Destroys an item, every tensor and name it owns, then writes null through handle.

One call for a whole composite subtree: the nodes’ tensor pointers were borrowed and are released here, so a caller that destroyed them individually would double-free.

Safety

• handle MUST be a valid, non-null pointer to a *mut HurrayItem produced by hurray_reader_next_item or hurray_file_reader_read_composite.
• That item MUST NOT have been destroyed already.
