strategyThe strategy with which to collect and publish elements.
optionsScheduleroptions to use for the strategy.
Return Value

Discussion
If the upstream publisher finishes before filling the buffer, this publisher sends an array of all the items it has received. This may be fewer than count elements. If the upstream publisher fails with an error, this publisher forwards the error to the downstream receiver instead of sending its output. Note: When this publisher receives a request for .max(n) elements, it requests .max(count * n) from the upstream publisher.
