Function reduce_w_cache

pub fn reduce_w_cache<Op, I, Cache>(
    _: Op,
    bitsets: I,
    _: Cache,
) -> Option<Reduce<Op, I, Cache>>
where
    Op: BitSetOp,
    I: Iterator + Clone,
    I::Item: BitSetInterface,
    Cache: ReduceCache,

reduce, using specific cache for iteration.

Cache applied to current operation only, so you can combine different cache types.

N.B. Alternatively, you can change Config::DefaultCache and use reduce.

Safety

Panics, if Cache capacity is smaller then sets len.
