Check whether this store contains a node with the given node ID.

fn add_node( &mut self, node: Node, safe: bool, ) -> Result<Option<Node>, NodeStoreError>

where Self: Sized,

Add a single node to this store. Setting ‘safe’ checks whether this node’s references exist and detects cyclic hierarchies.

where Self: Sized,

Extend this node store with new nodes. Setting ‘safe’ checks whether all node references exist and detects cyclic hierarchies after adding them to the store first.

where Self: Sized,

Node depth (i.e. the number of levels that exist above). Setting safe checks for cyclic hierarchies along the way. root_ids are nodes to consider as (additional) root nodes in this query. height determines the maximum height at which the ancestor is considered a root node.
