Struct opentelemetry::metrics::InstrumentBuilder

pub struct InstrumentBuilder<'a, T> { /* private fields */ }

Configuration for building a sync instrument.

Implementations

impl<'a, T> InstrumentBuilder<'a, T>

where T: TryFrom<Self, Error = MetricsError>,

pub fn with_description<S: Into<Cow<'static, str>>>( self, description: S, ) -> Self

Set the description for this instrument

pub fn with_unit<S: Into<Cow<'static, str>>>(self, unit: S) -> Self

Set the unit for this instrument.

Unit is case sensitive(kb is not the same as kB).

Unit must be:

• ASCII string
• No longer than 63 characters

pub fn try_init(self) -> Result<T>

Validate the instrument configuration and creates a new instrument.

pub fn init(self) -> T

Creates a new instrument.

Validate the instrument configuration and crates a new instrument.

Panics

Panics if the instrument cannot be created. Use try_init if you want to handle errors.
