Struct ProductHistogram 

pub struct ProductHistogram { /* private fields */ }

Typed handle for a registered product histogram.

Implementations

impl ProductHistogram

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

Creates a typed histogram from an opaque product metric handle.

Errors

Returns an error when the handle is not a histogram or its descriptor is unavailable.

pub const fn handle(&self) -> ProductMetricHandle

Returns the underlying opaque handle.

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

Observes a value in this histogram and logs recording failures.

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

Observes a value in this histogram and returns recording failures.

Errors

Returns an error when the label count is wrong or the histogram cannot be observed.

Trait Implementations

impl Clone for ProductHistogram

fn clone(&self) -> ProductHistogram

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProductHistogram

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

Formats the value using the given formatter.

impl PartialEq for ProductHistogram

fn eq(&self, other: &ProductHistogram) -> 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.
