Required Methods§

Source

fn node_generation(&self, id: NodeId) -> u32

Returns the current generation for a node index. Generation is incremented when an index is reused from the freelist, preventing stale slot entries from matching recycled nodes.

Source

fn insert_with_id( &mut self, id: NodeId, node: Box<dyn Node>, ) -> Result<(), NodeError>

Inserts a node with a pre-assigned ID.

This is used for virtual nodes whose IDs are allocated separately (e.g., via allocate_virtual_node_id()). Unlike create() which assigns a new ID, this method uses the provided ID.

Returns Ok(()) if successful, or an error if the ID is already in use.
