Function EncodeDurationAscending

pkg/util/encoding/encoding.go:1027–1039

EncodeDurationAscending encodes a duration.Duration value, appends it to the supplied buffer, and returns the final buffer. The encoding is guaranteed to be ordered such that if t1.Compare(t2) < 0 (or = 0 or > 0) then bytes.Compare will order them the same way after encoding.

(b []byte, d duration.Duration)

// be ordered such that if t1.Compare(t2) < 0 (or = 0 or > 0) then bytes.Compare
// will order them the same way after encoding.
func EncodeDurationAscending(b []byte, d duration.Duration) ([]byte, error) {
	sortNanos, months, days, err := d.Encode()
	if err != nil {
		// TODO(dan): Handle this using d.EncodeBigInt() and the
		// durationBigNeg/durationBigPos markers.
		return b, err
	}
	b = append(b, durationMarker)
	b = EncodeVarintAscending(b, sortNanos)
	b = EncodeVarintAscending(b, months)
	b = EncodeVarintAscending(b, days)
	return b, nil
