Snowflake structured OBJECT types can contain named, nullable or `NOT NULL` fields and recursively nested OBJECT types. The generic `Custom(Vec<String>)` representation loses these boundaries. This adds `DataType::Object(Vec<ColumnDef>)`, a Snowflake dialect capability, recursive parsing and formatting, and leaves unstructured `OBJECT` unchanged. Validated against: https://docs.snowflake.com/en/sql-reference/data-types-structured#structured-object-types Tests cover nested types, `NOT NULL` AST preservation, unstructured `OBJECT`, and malformed definitions. AI assistance: Codex was used to prepare the implementation and tests. -- This is an automated message from the Apache Git Service.
