pub async fn run_compare<FA, FutA, FB, FutB>(
a: Leg<'_, FA>,
b: Leg<'_, FB>,
concurrency: usize,
) -> (Vec<Outcome>, Vec<Outcome>)Expand description
Both pages of a comparison through one pool of workers: page a’s cases first, then b’s.
One pool rather than one per page, so --concurrency still means what it says — that many
requests in the air, whichever page they are for.
