pub struct AggregationResult {
    pub aggregate_properties: BTreeMap<String, Value>,
}
Expand description

The result of a single bucket from a Datastore aggregation query.

The keys of aggregate_properties are the same for all results in an aggregation query, unlike entity queries which can have different fields present for each result.

Fields§

§aggregate_properties: BTreeMap<String, Value>

The result of the aggregation functions, ex: COUNT(*) AS total_entities.

The key is the [alias][google.datastore.v1.AggregationQuery.Aggregation.alias] assigned to the aggregation function on input and the size of this map equals the number of aggregation functions in the query.
