Struct ProductGauge 

pub struct ProductGauge { /* private fields */ }

Typed handle for a registered product gauge.

Implementations

impl ProductGauge

pub fn from_handle(handle: ProductMetricHandle) -> ProductMetricResult<Self>

Creates a typed gauge from an opaque product metric handle.

pub const fn handle(&self) -> ProductMetricHandle

Returns the underlying opaque handle.

pub fn set(&self, label_values: &[&str], value: f64)

Sets this gauge and logs recording failures.

pub fn try_set( &self, label_values: &[&str], value: f64, ) -> ProductMetricResult<()>

Sets this gauge and returns recording failures.

pub fn add(&self, label_values: &[&str], value: f64)

Adds to this gauge and logs recording failures.

pub fn try_add( &self, label_values: &[&str], value: f64, ) -> ProductMetricResult<()>

Adds to this gauge and returns recording failures.

Trait Implementations

impl Clone for ProductGauge

fn clone(&self) -> ProductGauge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProductGauge

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

Formats the value using the given formatter.

impl PartialEq for ProductGauge

fn eq(&self, other: &ProductGauge) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
