sendSegments method
Queues one complete encoded frame, retaining 1–64 frozen native spans. At least one span must be nonempty. Caller handles remain valid on both success and rejection; callers may dispose them after acceptance. This copies no payload bytes and does not parse or transcode the wire encoding.
Implementation
void sendSegments(int connectionId, List<NativeOwnedBuffer> segments) {
_check(_ownedSegments.submit(connectionId, segments, tracked: false));
}
