Struct GraphSnapshot 

pub struct GraphSnapshot { /* private fields */ }

MVCC-lite read-only snapshot for graph data isolation.

Provides safe, read-only access to a point-in-time view of the graph with its own SQLite connection to ensure database consistency.

Implementations

impl GraphSnapshot

pub fn new(state: Arc<SnapshotState>, db_path: &str) -> SqliteResult<Self>

Create a new graph snapshot

Arguments

• state - Immutable snapshot state
• db_path - Path to SQLite database

Returns

Result containing GraphSnapshot or error
