Trait opentelemetry::sdk::export::metrics::InstrumentationLibraryReader

pub trait InstrumentationLibraryReader {
    fn try_for_each(

        f: &mut dyn FnMut(&InstrumentationLibrary, &mut dyn Reader)
    ) -> Result<(), MetricsError>;
}

Available on crate feature metrics only.

InstrumentationLibraryReader is an interface for exporters to iterate over one instrumentation library of metric data at a time.

Required Methods

fn try_for_each(
    &self,
    f: &mut dyn FnMut(&InstrumentationLibrary, &mut dyn Reader)
) -> Result<(), MetricsError>

ForEach calls the passed function once per instrumentation library, allowing the caller to emit metrics grouped by the library that produced them.
