Expand description

ScalarImpl embeds all possible scalars in the evaluation framework.

Note: ScalarImpl doesn’t contain all information of its DataType, so sometimes they need to be used together. e.g., for Struct, we don’t have the field names in the value.

See for_all_variants for the definition.
