# Type Alias Nemo Relay Native Async Next Stream Cb

> Receives one downstream stream item. `chunk_json` is non-null for a chunk, `error` is non-null for failure or consumer cancellation, and `done` marks clean completion. Unless the callback itself returns `false`, the host invokes one terminal callback so the plugin can reclaim `user_data`. Return `false` to cancel downstream production after the current callback; in that case, reclaim `user_data` before returning because no later callback is made.
