Counts features in a given source that intersect the given geometry.
The source to identify.
The geometry to match against.
Optionaloptions: IdentifyOptionsOptions that affect the identify operation.
An iterable of tasks/CountResult!CountResults containing count results. If canceled, the provider may reject the returned promise with an instance of support/Cancellable!Cancellation, though it may still fulfill with count results instead.
