count
abstract suspend fun count(name: String, filter: Filter?, exact: Boolean, routeAffinity: String? = null): Long
Count points, optionally filtered (POST /collections/{name}/points/count).
routeAffinity is Qdrant's X-Qdrant-Route-Affinity read hint, sent as a header rather than in the body. The request models carry their own; count and retrieve have none, so it is a parameter.
