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

Configuration for building a sync instrument.

Implementations§

source§

impl<'a, T> InstrumentBuilder<'a, T>where T: TryFrom<Self, Error = MetricsError>,

source

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

Set the description for this instrument

source

pub fn with_unit(self, unit: Unit) -> 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
source

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

Validate the instrument configuration and creates a new instrument.

source

pub fn init(self) -> T

Creates a new instrument.

This method reports configuration errors but still returns the instrument.

Panics

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