Struct Percentile 

pub struct Percentile {
    pub quantile: f64,
    /* private fields */
}

Percentile aggregation (sort-based, exact)

Computes an exact percentile using sort + linear interpolation. Window sizes in CEP are bounded, so sort-based is correct and efficient.

Examples

• Percentile::new(0.5) = median
• Percentile::new(0.95) = p95
• Percentile::new(0.99) = p99

Fields

quantile: f64

Implementations

impl Percentile

pub fn new(quantile: f64) -> Self

Trait Implementations

impl AggregateFunc for Percentile

fn name(&self) -> &str

Returns the name of this aggregation function (e.g., “sum”, “avg”).

fn apply(&self, events: &[Event], field: Option<&str>) -> Value

Apply the aggregation to a slice of events.

fn apply_refs(&self, events: &[&Event], field: Option<&str>) -> Value

Apply aggregation to event references (internal helper)

fn apply_shared(&self, events: &[SharedEvent], field: Option<&str>) -> Value

Apply aggregation to shared events (avoids cloning in hot paths).

fn apply_columnar( &self, buffer: &mut ColumnarBuffer, field: Option<&str>, ) -> Value

Apply aggregation to columnar buffer (SIMD-optimized for numeric aggregations).

impl Debug for Percentile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
