Struct opentelemetry::metrics::Descriptor

pub struct Descriptor { /* fields omitted */ }

This is supported on crate feature metrics only.

Descriptor contains all the settings that describe an instrument, including its name, metric kind, number kind, and the configurable options.

Implementations

impl Descriptor

pub fn new(
    name: String,
    instrumentation_name: &'static str,
    instrumentation_version: Option<&'static str>,
    instrument_kind: InstrumentKind,
    number_kind: NumberKind
) -> Self

Create a new descriptor

pub fn name(&self) -> &str

The metric instrument's name.

pub fn instrument_kind(&self) -> &InstrumentKind

The specific kind of instrument.

pub fn number_kind(&self) -> &NumberKind

NumberKind returns whether this instrument is declared over int64, float64, or uint64 values.

pub fn description(&self) -> Option<&String>

A human-readable description of the metric instrument.

pub fn set_description(&mut self, description: String)

Assign a new description

pub fn unit(&self) -> Option<&str>

Unit describes the units of the metric instrument.

pub fn instrumentation_name(&self) -> &'static str

The name of the library that provided instrumentation for this instrument.

pub fn attribute_hash(&self) -> u64

The pre-computed hash of the descriptor data
