Enum NodeOwnership 

pub enum NodeOwnership {
    TreeOwned,
    CallerOwned,
    Borrowed,
    Unlinked,
}

The ownership state of a tree node.

This is used internally to track whether a node pointer is:

• Part of a document tree (owned by the document)
• A standalone node (caller-owned, must be freed or adopted)
• A borrowed reference (must not be freed)

Variants

TreeOwned

The node is owned by its parent document or parent node. It will be freed when the document is freed. Callers must NOT free it directly.

CallerOwned

The node is standalone (not attached to any document). The caller owns it and must free it or attach it to a tree.

Borrowed

The node is borrowed from a tree. The caller must NOT free it.

Unlinked

The node has been unlinked from its tree. The caller now owns it and must free it or re-attach it.
