- Add AttrSchema dataclass with defensive copying - Create process_attr_key_args() helper to eliminate duplication - Refactor dtype inference and SQLAlchemy mapping to use dictionaries - Add overloaded method signatures for convenience and schema modes - Replace _node/edge_attr_keys lists with _attr_schemas dicts - Add comprehensive test suite (16 tests passing) Breaking change: dtype parameter now required. Next phase will update all calling sites throughout the codebase.
…add_edge_attr_key This is a breaking change that requires dtype (polars.DataType) to be explicitly specified when adding attribute keys to graphs. Core changes: - Add AttrSchema dataclass to store key, dtype, and default_value together - Add utility functions: infer_default_value_from_dtype, polars_dtype_to_sqlalchemy_type, validate_default_value_dtype_compatibility, and process_attr_key_args - Update BaseGraph abstract methods with overloaded signatures supporting both direct parameters and AttrSchema objects - Replace _node_attr_keys/_edge_attr_keys lists with _node_attr_schemas dicts in RustWorkXGraph and SQLGraph - Remove _boolean_columns tracking in SQLGraph (now uses AttrSchema) - Fix _polars_schema_override to use == instead of isinstance for pl.Boolean check Backend implementations: - RustWorkXGraph: Use process_attr_key_args helper, store AttrSchema objects - SQLGraph: Use process_attr_key_args helper, pass AttrSchema to _add_new_column - GraphView: Delegate to root graph with all parameters preserved - Add dtype inference fallback for complex objects that polars can't parse Updated all callers: - Graph methods: from_other(), match() - Node operators: RandomNodes, RegionPropsNodes, GenericNodesOperator - Edge operators: DistanceEdges, GenericEdgesOperator - Solvers: ILPSolver, NearestNeighborsSolver - IO: numpy_array, ctc
Update all test files to use the new required dtype parameter for add_node_attr_key and add_edge_attr_key methods. Key test fixes: - Add dtype inference logic in test_add_node_attr_key based on value type - Fix bbox attribute calls to use pl.Array(pl.Int64, size) instead of passing numpy arrays as dtype - Add missing polars imports where needed - Fix argument order from (key, False, dtype=pl.Boolean) to (key, pl.Boolean, default_value=False)
