Module intern 

Available on (crate features worker-pool or worker-batch or worker) and crate feature worker-batch only.

Field name interning for the batch processing engine.

Deduplicates field name strings across an entire batch. The first occurrence of a field name allocates an Arc<str>; all subsequent occurrences get a cheap Arc::clone (~2 ns). Thread-safe via DashMap – safe for concurrent access from rayon worker threads.
