Struct GroupStats 

pub struct GroupStats {
    pub count: u64,
    pub sum: f64,
    pub min: Option<IndexValue>,
    pub max: Option<IndexValue>,
}

One group’s live statistics.

Fields

count: u64

Rows in the group.

sum: f64

Sum of the aggregated field (f64 accumulation — the i64 overflow guard; precision bounds documented).

min: Option<IndexValue>

Exact minimum (None only when count == 0).

max: Option<IndexValue>

Exact maximum.

Implementations

impl GroupStats

pub fn avg(&self) -> Option<f64>

Derived average.

Trait Implementations

impl Clone for GroupStats

fn clone(&self) -> GroupStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GroupStats

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

Formats the value using the given formatter.

impl PartialEq for GroupStats

fn eq(&self, other: &GroupStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
