// Options used to write CSV files. Fields with non-null Java defaults are
// always sent; fields marked `optional` preserve unset-ness so the Rust side
// can leave a DataFusion default in place. `FileCompressionType` is shared
// with the read side since the codec set is identical. Note: `partition_cols`
// is sent as a repeated string so an empty list (the default) round-trips
// unambiguously.
