Enum MetricValue 

#[non_exhaustive]
pub enum MetricValue {
    Double(f64),
    String(String),
    Long(i64),
    Int(i32),
}

The type-erased value of a metric.

Java’s Metric.metricValue() returns Object, which may be a measurable Double or a non-measurable gauge value of any type. This enum captures the value kinds the consumer metrics produce.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Double(f64)

A measurable (or Double-valued gauge) reading.

String(String)

A string-valued gauge reading.

Long(i64)

A long-valued gauge reading.

Int(i32)

An integer-valued gauge reading.

Implementations

impl MetricValue

pub fn as_double(&self) -> Option<f64>

Returns the value as an f64 if it is a MetricValue::Double.

Trait Implementations

impl Clone for MetricValue

fn clone(&self) -> MetricValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricValue

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

Formats the value using the given formatter.

impl PartialEq for MetricValue

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