Every remaining matching activity, continuing from where reading stopped.
Releases what this sequence reads from. Idempotent.
Reading to the end releases it for you. Stopping early deliberately does not, so
all() still works afterwards — call this once you are done with such a sequence, or
leave it to be collected.
An async-iterable sequence of activities matching a filter.
Returned by ActivitiesResource.list:
Read ActivityStream.total for the number of activities matching the filter, or call ActivityStream.all to collect what is left into an array.
