Struct Collector

pub struct Collector<'a, T: IsCollector> { /* private fields */ }

A collector is a wrapper around a metric with some attributes.

Please use the #[metrics] macro to create collectors.

Implementations

impl<'a, T: IsCollector> Collector<'a, T>

pub fn new(attributes: Vec<KeyValue>, collector: &'a T) -> Self

Wraps a given collector with the provided attributes.

This is typically used internally for constructing types when using the #[metrics] module or function attribute.

pub fn inner(&self) -> &'a T

Returns the inner collector.

impl<'a> Collector<'a, Counter<u64>>

pub fn incr(&self)

Increments the counter by one.

pub fn incr_by(&self, value: u64)

Increments the counter by the given value.

impl<'a> Collector<'a, Counter<f64>>

pub fn incr(&self)

Increments the counter by one.

pub fn incr_by(&self, value: f64)

Increments the counter by the given value.

impl<'a> Collector<'a, Gauge<u64>>

pub fn record(&self, value: u64)

Sets the value of the gauge.

impl<'a> Collector<'a, Gauge<f64>>

pub fn record(&self, value: f64)

Sets the value of the gauge.

impl<'a> Collector<'a, Gauge<i64>>

pub fn record(&self, value: i64)

Sets the value of the gauge.

impl<'a> Collector<'a, Histogram<u64>>

pub fn observe(&self, value: u64)

Observes a new value.

impl<'a> Collector<'a, Histogram<f64>>

pub fn observe(&self, value: f64)

Observes a new value.

impl<'a> Collector<'a, UpDownCounter<i64>>

pub fn incr(&self)

Increments the counter by one.

pub fn incr_by(&self, value: i64)

Increments the counter by the given value.

pub fn decr(&self)

Decrements the counter by one.

pub fn decr_by(&self, value: i64)

Decrements the counter by the given value.

impl<'a> Collector<'a, UpDownCounter<f64>>

pub fn incr(&self)

Increments the counter by one.

pub fn incr_by(&self, value: f64)

Increments the counter by the given value.

pub fn decr(&self)

Decrements the counter by one.

pub fn decr_by(&self, value: f64)

Decrements the counter by the given value.
