Struct sosistab::StatsGatherer

pub struct StatsGatherer { /* fields omitted */ }

A generic statistics gatherer, logically a string-keyed map of f64-valued time series. It has a fairly cheap Clone implementation, allowing easy “snapshots” of the stats at a given point in time. The Default implementation creates a no-op that does nothing.

Implementations

impl StatsGatherer

pub fn new_active() -> Self

Creates a usable statistics gatherer. Unlike the Default implementation, this one actually does something.

pub fn update(&self, stat: &str, val: f32)

Updates a statistical item.

pub fn increment(&self, stat: &str, delta: f32)

Increments a statistical item.

pub fn get_last(&self, stat: &str) -> Option<f32>

Obtains the last value of a statistical item.

pub fn get_timeseries(&self, stat: &str) -> Option<TimeSeries>

Obtains the whole TimeSeries, taking ownership of a snapshot.

pub fn iter(&self) -> impl Iterator<Item = (String, TimeSeries)>

Iterates through all the TimeSeries in this stats gatherer.
