Module nested_struct 

Functions

adapt_batch_to_schema

Adapts a RecordBatch to conform to target_schema, verifying that each target field type contains the incoming column data type (as verified by arrow::datatypes::DataType::contains) and transforms the metadata/types of differing columns to match target_schema without copying primitive buffer data.

cast_column

Cast a column to match the target field type, with special handling for nested structs.

has_one_of_more_common_fields

Check if two field lists have at least one common field by name.

requires_nested_struct_cast

Returns true if casting from source_type to target_type requires name-based nested struct casting logic, rather than Arrow’s standard cast.

validate_data_type_compatibility

Validates that source_type can be cast to target_type, recursively handling container types that wrap structs.

validate_struct_compatibility

Validates compatibility between source and target struct fields for casting operations.
