object
Describes a typed object via a dictionary of parsers. DDataParser.object() builds a structured schema, applies each child parser, aggregates errors with their path (user.address.city), and returns the validated immutable value.
Interactive example
Parameters
shape: dictionary{ key: DataParser }(all available parsers are accepted, including those composed viapipe).checkers:checkerRefineand custom helpers to validate the complete result (e.g. check inter-field dependencies).errorMessage: general message used when the input is not a valid object.
Return value
A DataParserObject with the methods parse, asyncParse, exec, asyncExec, addChecker, clone. schema.parse(data) returns DEither.success<Shape> if everything passes or DEither.error<DataParserError> grouping all issues.
