Struct GhostNode 

pub struct GhostNode {
    pub node_id: NodeId,
    pub shard_id: ShardId,
    pub label: String,
    pub full_data: Option<NodeData>,
}

A ghost node - minimal reference to a node on another shard.

Ghost nodes are placeholders for nodes that exist on remote shards. They enable local graph traversal to continue even when edges cross shard boundaries. The full data can be fetched lazily when needed.

Fields

node_id: NodeId

The actual node ID (same as on the owning shard).

shard_id: ShardId

The shard that owns this node.

label: String

The node’s label (cached for display/search).

full_data: Option<NodeData>

Full data fetched lazily when needed for operations.

Implementations

impl GhostNode

pub fn new(node_id: NodeId, shard_id: ShardId, label: String) -> Self

Create a new ghost node reference.

pub fn is_resolved(&self) -> bool

Check if the full data has been fetched.

pub fn resolve(&mut self, data: NodeData)

Resolve this ghost node with full data from the remote shard.
