DatapointDecoder.Unmarshal

func (d datasets.DatapointDecoder) Unmarshal(
    descriptor *datasets.DatapointDescriptor,
    data []byte,
) (map[string]any, error)

Decode a raw protobuf datapoint into a JSON-like map with configurable protobuf decoding options.

Parameters

descriptor · *datasets.DatapointDescriptor · required

The descriptor returned by NewDatapointDescriptor.

data · []byte · required

The raw protobuf datapoint bytes returned by a datapoint query.

Decoder options

AllowPartial · bool

Allow messages that are missing required fields.

DiscardUnknown · bool

Ignore unknown fields in the raw protobuf message.

Resolver

Override the resolver used to look up message and extension types.

RecursionLimit · int

Limit how deeply nested messages may be decoded. A zero value uses the protobuf default.

Returns

A map of datapoint fields, or an error if the raw datapoint cannot be decoded.

Go

decoder := datasets.DatapointDecoder{
    DiscardUnknown: true,
}

datapoint, err := decoder.Unmarshal(descriptor, data)
if err != nil {
    return err
}
