Function block_diff_added_with_parent

    storage: S,
    prev: Option<Cid>,
    next: Cid,
    block_links: BlockLinks,
    look_ahead_depth: Option<u8>,

Find added references in blocks with its parent. This diff works recursively - all added Cid at any depth will be returned. However there is a look-ahead depth limit, how many nodes are looked down to reuse references (defaults to 1).

Args

• follow - Whether to follow this Cid or not.
