Struct Counter 

pub struct Counter { /* private fields */ }

A counter metric instrument that optionally tracks values in memory for heartbeating.

Implementations

impl Counter

pub fn new( inner: Arc<dyn MetricAttributable<Box<dyn CounterBase>> + Send + Sync>, ) -> Self

Create a new counter from an attributable metric source.

pub fn new_with_in_memory( primary: Arc<dyn MetricAttributable<Box<dyn CounterBase>> + Send + Sync>, in_memory: HeartbeatMetricType, ) -> Self

Create a new counter with an additional in-memory tracker for heartbeat reporting.

pub fn add(&self, value: u64, attributes: &MetricAttributes)

Increment the counter by value with the given attributes.

pub fn update_attributes(&mut self, new_attributes: MetricAttributes)

Replace the attributes on the primary metric.

Trait Implementations

impl Clone for Counter

fn clone(&self) -> Counter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CounterBase for Counter

fn adds(&self, value: u64)

Increment the counter by value.

impl MetricAttributable<Counter> for Counter

fn with_attributes( &self, attributes: &MetricAttributes, ) -> Result<Counter, Box<dyn Error>>

Replace any existing attributes on this metric with new ones, and return a new copy of the metric, or a base version, which can be used to record values.
