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

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