isNullable :: DataType -> Bool Source #
columnType :: SQLType a -> DataType Source #
unsafeCastType :: SQLType a -> SQLType b Source #
arrayType' :: DataType -> DataType Source #
structField :: Text -> DataType -> StructField Source #
structType :: [StructField] -> DataType Source #
structTypeFromFields :: [(FieldName, DataType)] -> Try StructType Source #
structTypeTuple :: NonEmpty DataType -> StructType Source #
Builds a type that is a tuple of all the given types.
Following the Spark and SQL convention, the indexing starts at 1.
structTypeTuple' :: NonEmpty DataType -> DataType Source #
Returns a data type instead (the most common use case)
Note that unlike Spark and SQL, the indexing starts from 0.
structName :: StructType -> Text Source #
