def collect[M[_]](upTo: Int, stopOnError: Boolean)(implicit cbf: CanBuildFrom[M[_], T, M[T]], ec: ExecutionContext): Future[M[T]]

Collects all the documents into a collection of type M[T].
Collects all the documents into a collection of type M[T]. Given the stopOnError parameter (which defaults to true), the resulting Future may fail if any non-fatal exception occurs. If set to false, all the documents that caused exceptions are skipped. Up to maxDocs returned by the database may be processed. If stopOnError is false, then documents that cause error are dropped, so the result may contain a little less than maxDocs even if maxDocs documents were processed.
upTo
Collect up to upTo documents.
stopOnError
States if the Future should fail if any non-fatal exception occurs.
Example:
```
val cursor = collection.find(query, filter).cursor[BSONDocument]
// return the 3 first documents in a Vector[BSONDocument].
val vector = cursor.collect[Vector](3)
```
