Expand description

Computes the conjunction of an iterator of Boolean futures.

All inputs are polled concurrently and false short-circuits the operation. An empty iterator resolves to true. An exact upper size hint of thirty or fewer keeps a stack-resident boxed slice polled in order; anything else, an absent hint included, builds a FuturesOrdered polled by readiness.
