// Options used to write JSON 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 and the CSV writer since the codec set is identical.
// `partition_cols` is sent as a repeated string so an empty list (the
// default) round-trips unambiguously.
//
// The output is always newline-delimited JSON (NDJSON) -- DataFusion's JSON
// writer only emits NDJSON, so the read-side `newline_delimited` toggle has
// no equivalent here.
