pub fn parallel_scan_default<T, U, F>(input: &[T], worker: F) -> Vec<U>Expand description
Phase 3.4 wiring entry point. Calls parallel_scan with
default_parallelism() worker count. Used by the runtime
scan executor when its planner cost model decides parallel
is profitable (input size > MIN_PARALLEL_ROWS). Saves the
caller from manually threading the worker count through.
