What does rs-trafilatura with crawl4ai actually do?

Swaps in a Rust extractor for page-type classification, quality scoring, and clean content pulls—JSON out, LLM-ready.

Is rs-trafilatura faster than crawl4AI's default?

Yes, threaded Rust via PyO3—no GIL blocks, scales async crawls without hiccups.

Will rs-trafilatura replace LLM extraction entirely?

No, 8% low-quality pages still need fallback, but it handles 92% heuristically.
