Struct SnapshotState 

pub struct SnapshotState {
    pub outgoing: HashMap<NodeId, Vec<NodeId>>,
    pub incoming: HashMap<NodeId, Vec<NodeId>>,
    pub created_at: SystemTime,
}

Immutable snapshot state containing cloned adjacency data

This structure stores complete copies of adjacency maps to ensure true isolation - snapshots are unaffected by subsequent writes.

Fields

outgoing: HashMap<NodeId, Vec<NodeId>>

Immutable copy of outgoing adjacency map

incoming: HashMap<NodeId, Vec<NodeId>>

Immutable copy of incoming adjacency map

created_at: SystemTime

Snapshot creation timestamp for debugging

Implementations

impl SnapshotState

pub fn new( outgoing: &HashMap<NodeId, Vec<NodeId>>, incoming: &HashMap<NodeId, Vec<NodeId>>, ) -> Self

Create a new snapshot state by cloning adjacency maps

Arguments

• outgoing - Current outgoing adjacency map to clone
• incoming - Current incoming adjacency map to clone

Returns

New SnapshotState with immutable cloned data

pub fn node_count(&self) -> usize

Get the number of nodes in this snapshot

pub fn edge_count(&self) -> usize

Get the number of edges in this snapshot

pub fn contains_node(&self, node_id: NodeId) -> bool

Check if a node exists in this snapshot

pub fn get_outgoing(&self, node_id: NodeId) -> Option<&Vec<NodeId>>

Get outgoing neighbors for a node in this snapshot

pub fn get_incoming(&self, node_id: NodeId) -> Option<&Vec<NodeId>>

Get incoming neighbors for a node in this snapshot
