Source§fn name(&self) -> &'static str
fn name(&self) -> &'static str
Returns the name of this aggregation function (e.g., “sum”, “avg”).
Source§fn apply(&self, events: &[Event], _field: Option<&str>) -> Value
fn apply(&self, events: &[Event], _field: Option<&str>) -> Value
Apply the aggregation to a slice of events. Read more

) -> Value
fn apply_columnar( &self, buffer: &mut ColumnarBuffer, _field: Option<&str>, ) -> Value
Apply aggregation to columnar buffer (SIMD-optimized for numeric aggregations). Read more
