Function ExpandSamples

storage/series.go:452–454

ExpandSamples iterates over all samples in the iterator, buffering all in slice. Optionally it takes samples constructor, useful when you want to compare sample slices with different sample implementations. if nil, sample type from this package will be used. For float sample, NaN values are replaced

(iter chunkenc.Iterator, newSampleFn func(st, t int64, f float64, h *histogram.Histogram, fh *histogram.FloatHistogram) chunks.Sample)

// sample implementations. if nil, sample type from this package will be used.
// For float sample, NaN values are replaced with -42.
func ExpandSamples(iter chunkenc.Iterator, newSampleFn func(st, t int64, f float64, h *histogram.Histogram, fh *histogram.FloatHistogram) chunks.Sample) ([]chunks.Sample, error) {
	return expandSamples(iter, true, newSampleFn)
}

// ExpandSamplesWithoutReplacingNaNs is same as ExpandSamples but it does not replace float sample NaN values with anything.
func ExpandSamplesWithoutReplacingNaNs(iter chunkenc.Iterator, newSampleFn func(st, t int64, f float64, h *histogram.Histogram, fh *histogram.FloatHistogram) chunks.Sample) ([]chunks.Sample, error) {
