Function write_edge_map

atomic-core/src/apply/edge.rs:80–102

Write an EdgeUpdate atom to the graph. Modifies existing edges in the graph. This is primarily used for: - Marking content as deleted (adding DELETED flag) - Undeleting content (removing DELETED flag) - Changing edge properties Edges are written to the global GRAPH and INODE_GRAPH tables. # Arguments `txn` - Write transaction for graph modifications `workspace` - Workspace for tracking state a
