func MarshalFloat ¶ added in v0.44.0

func MarshalFloat(f float64, stream *jsoniter.Stream)

MarshalFloat marshals a float value using the passed jsoniter stream.

func MarshalHistogram ¶ added in v0.44.0

func MarshalHistogram(h *histogram.FloatHistogram, stream *jsoniter.Stream)

MarshalHistogram marshals a histogram value using the passed jsoniter stream. It writes something like:

{
    "count": "42",
    "sum": "34593.34",
    "buckets": [
      [ 3, "-0.25", "0.25", "3"],
      [ 0, "0.25", "0.5", "12"],
      [ 0, "0.5", "1", "21"],
      [ 0, "2", "4", "6"]
    ]
}

The 1st element in each bucket array determines if the boundaries are inclusive (AKA closed) or exclusive (AKA open):

0: lower exclusive, upper inclusive
1: lower inclusive, upper exclusive
2: both exclusive
3: both inclusive

The 2nd and 3rd elements are the lower and upper boundary. The 4th element is the bucket count.

func MarshalTimestamp ¶

func MarshalTimestamp(t int64, stream *jsoniter.Stream)

MarshalTimestamp marshals a point timestamp using the passed jsoniter stream.
