Struct metrics::SimpleStat

pub struct SimpleStat<T: NumberType> {
    count: u64,
    sum: T,
    min: T,
    max: T,
}

Light weight stat struct that helps you get aggregate stats like min, max, average, count and sum. Median and standard deviation are intentionally excluded to keep the structure light weight.

Fields

count: u64

sum: T

min: T

max: T

impl<T: NumberType> SimpleStat<T>

pub fn add(&mut self, value: T)

Trait Implementations

impl<T: NumberType> Debug for SimpleStat<T>

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

Formats the value using the given formatter.

impl<T: NumberType> Default for SimpleStat<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq + NumberType> PartialEq for SimpleStat<T>

fn eq(&self, other: &SimpleStat<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: NumberType> SummaryStats<T> for SimpleStat<T>

fn count(&self) -> u64

Count of data points that tracked.

fn sum(&self) -> Option<T>

Sum of all data points. Returns None if count is zero.

fn min(&self) -> Option<T>

Minimum value of data points. Returns None if count is zero.

fn max(&self) -> Option<T>

Maximum value of data points. Returns None if count is zero.

fn average(&self) -> Option<T>

Average value of data points. Returns None if count is zero.
