Struct MetricStore 

pub struct MetricStore { /* private fields */ }

Central store for all incoming metrics, organized by ID.

Implementations

impl MetricStore

pub fn new() -> Self

Creates a new empty metric store.

pub fn push(&mut self, id: MetricId, value: f32)

Pushes a new sample for the given metric.

pub fn get_average(&self, id: &MetricId) -> f32

Returns the average value for a metric, or 0.0 if not found.

pub fn get_trend(&self, id: &MetricId) -> f32

Returns the trend for a metric, or 0.0 if not found.

pub fn get_variance(&self, id: &MetricId) -> f32

Returns the variance for a metric, or 0.0 if not found.

High variance in frame times is a strong stutter indicator.

pub fn get_max(&self, id: &MetricId) -> f32

Returns the maximum value for a metric, or 0.0 if not found.

pub fn get_min(&self, id: &MetricId) -> f32

Returns the minimum value for a metric, or 0.0 if not found.

pub fn get_sample_count(&self, id: &MetricId) -> usize

Returns the sample count for a metric, or 0 if not found.

Trait Implementations

impl Debug for MetricStore

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

Formats the value using the given formatter.

impl Default for MetricStore

fn default() -> MetricStore

Returns the “default value” for a type.
