Struct ProducerRecordOptions 

#[non_exhaustive]
pub struct ProducerRecordOptions<K, V> { /* private fields */ }

The parameters of Java’s widest ProducerRecord constructor (ProducerRecord(String, Integer, Long, K, V, Iterable<Header>), ProducerRecord.java:69).

This struct has no Java counterpart (DoD #7). It exists solely to satisfy CLAUDE.md §2’s cap on derived overload names: that constructor differs from the group’s intersection {topic, value} by four parameters — partition, timestamp, key, headers — so the cap fires and this struct becomes the method’s only parameter, carrying every Java parameter including the intersection’s own.

It deliberately has no Default. topic and value are what even Java’s narrowest constructor (:142) takes from its caller, so neither has a Java-derived default — and a synthesised empty topic would silently send the record nowhere. Construct it with ProducerRecordOptionsBuilder::new and set them: ProducerRecordOptionsBuilder::build returns an error if any of topic, value was not set.
