Struct holochain_metrics::stats::OnlineStats

pub struct OnlineStats { /* fields omitted */ }

An extension of stats::OnlineStats that also incrementally tracks max and min values.

Methods

impl OnlineStats

pub fn map<__SHRINKWRAP_T, __SHRINKWRAP_F: FnMut(OnlineStats) -> __SHRINKWRAP_T>(
    self,
    f: __SHRINKWRAP_F
) -> __SHRINKWRAP_T

Map a function over the wrapped value, consuming it in the process.

pub fn map_ref<__SHRINKWRAP_T, __SHRINKWRAP_F: FnMut(&OnlineStats) -> __SHRINKWRAP_T>(
    &self,
    f: __SHRINKWRAP_F
) -> __SHRINKWRAP_T

Map a function over the wrapped value without consuming it.

impl OnlineStats

pub fn empty() -> Self

An initial empty statistic.

pub fn add(&mut self, value: f64)

Adds a value to the running statistic.

Return the current mean.

pub fn stddev(&self) -> f64

Return the current standard deviation.

pub fn variance(&self) -> f64

Return the current variance.

pub fn len(&self) -> usize

Returns the number of data points.
