Expand description

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

Required Methods§

source

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

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