Function extract_routing_field 

Source

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

Extract a routing field from raw JSON bytes using SIMD.

Uses sonic_rs::get_from_slice for zero-copy extraction. The error path (distinguishing a missing field from invalid JSON) requires a full validity check and is intentionally cold.

§Behaviour

  • Ok string value -> Found(string)
  • Ok non-string value -> Found(raw_str) (raw JSON)
  • Err with is_not_found() -> Missing
  • Err other -> ParseError
