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)

MetricsFrom creates a pmetric.Metrics from the given Arrow Record.

Important Note: This function doesn't take ownership of the record, so the record must be released by the caller.
