Decode the specified `json` into the specified `result`. If the optionally specified `errorStream` is non‐null, a description of any errors that occur during parsing will be output to this stream. If the optionally specified `options` argument is not present, treat it as a default‐constructed `DatumDecoderOptions`. Return 0 on success, and a negative value if `json` could not be decoded (either because it is ill‐formed, or if a constraint imposed by `option` is violated). An error status will be returned if `json` contains arrays or objects that are nested beyond a depth configured by `options.maxNestedDepth()`. The mapping of types in JSON to the types supported by `Datum` is described in []Types).
