Changelog

0.1.2.3

  • Move DuckDBColumnType requirement for ToField to DuckValue

0.1.2.2

  • Add support for reading and writing arrays.
  • Added Database.DuckDB.Simple.Generic with GHC generics helpers (GToField/GFromField) for encoding records as DuckDB STRUCTs and sum types as UNIONs, plus a ViaDuckDB newtype for convenient @DerivingVia@ support.
  • Added DuckValue instances for [], Array Int a, and Map k v to enable lists, arrays, and maps as fields within generically-encoded structs and unions.
  • Documented struct/union generic support; added richer tests covering database round-trips and deriving-via examples.
  • Support decoding and binding STRUCT and UNION values via new StructValue/UnionValue helpers and corresponding FromField/ToField instances.

0.1.2.0

  • Added LIST/MAP coverage note: LIST columns decode into Haskell lists and MAP columns into strict Map k v, with matching parameter bindings via ToField.
  • Taught FromField to interpret FieldBigNum as Integer/Natural and added matching ToField instances for BigNum, Integer, and Natural so BIGNUM parameters round-trip without truncation.
  • Added duckdbColumnType helper and DuckDBColumnType class, exposing the DuckDB column type associated with each ToField instance.
  • Fixed UUID decoding by undoing DuckDB’s upper-word bias and added a UUID round-trip regression test.
  • Fixed BIT encoding and decoding

0.1.1.2

  • Broadened FieldValue and FromField coverage to handle all DuckDB scalar types, including intervals, HUGEINT/UHUGEINT, decimals (with metadata), time/timestamp with additional precisions, timezone-aware values, bit strings, bignums, and enums.
  • Fixed enum decoding for both query results and scalar-function inputs by honouring the logical type’s underlying storage width (uint8/uint16/uint32).
  • Ensured decimal vectors read accurate width/scale metadata when materializing results or invoking UDFs.
  • Added unsigned ToField bindings that route through DuckDB’s native uint creators and exposed FromField Word.
  • Expanded the test suite with regressions covering unsigned round-trips, huge integers, intervals, decimals, and timezone-aware values.

0.1.0.0

  • Initial release
