Functions

func AppendQuantileValuesInto

func AppendQuantileValuesInto(quantileSlice pmetric.SummaryDataPointValueAtQuantileSlice, record arrow.Record, ndpIdx int, ids *QuantileValueIds) error

func AppendUnivariateEHistogramDataPointBucketsInto

func AppendUnivariateEHistogramDataPointBucketsInto(dpBuckets pmetric.ExponentialHistogramDataPointBuckets, ehdp *array.Struct, ids *EHistogramDataPointBucketsIds, row int) error

func MetricsFrom

func MetricsFrom(record arrow.Record, relatedData *RelatedData) (pmetric.Metrics, error)
