	// Metadata about the result set, such as row type information.
	// Only present in the first response.
	Metadata *ResultSetMetadata `protobuf:"bytes,1,opt,name=metadata,proto3" json:"metadata,omitempty"`
	// A streamed result set consists of a stream of values, which might
	// be split into many `PartialResultSet` messages to accommodate
	// large rows and/or large values. Every N complete values defines a
	// row, where N is equal to the number of entries in
	// [metadata.row_type.fields][google.spanner.v1.StructType.fields].
	//
	// Most values are encoded based on type as described
	// [here][google.spanner.v1.TypeCode].
	//
	// It is possible that the last value in values is "chunked",
	// meaning that the rest of the value is sent in subsequent
	// `PartialResultSet`(s). This is denoted by the [chunked_value][google.spanner.v1.PartialResultSet.chunked_value]
	// field. Two or more chunked values can be merged to form a
	// complete value as follows:
	//
	//   - `bool/number/null`: cannot be chunked
	//   - `string`: concatenate the strings
	//   - `list`: concatenate the lists. If the last element in a list is a
	//     `string`, `list`, or `object`, merge it with the first element in
	//     the next list by applying these rules recursively.
	//   - `object`: concatenate the (field name, field value) pairs. If a
	//     field name is duplicated, then apply these rules recursively
	//     to merge the field values.
	//
	// Some examples of merging:
	//
	//	# Strings are concatenated.
	//	"foo", "bar" => "foobar"
	//
	//	# Lists of non-strings are concatenated.
	//	[2, 3], [4] => [2, 3, 4]
	//
	//	# Lists are concatenated, but the last and first elements are merged
	//	# because they are strings.
	//	["a", "b"], ["c", "d"] => ["a", "bc", "d"]
	//
	//	# Lists are concatenated, but the last and first elements are merged
	//	# because they are lists. Recursively, the last and first elements
	//	# of the inner lists are merged because they are strings.
	//	["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]
	//
	//	# Non-overlapping object fields are combined.
	//	{"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"}
	//
	//	# Overlapping object fields are merged.
	//	{"a": "1"}, {"a": "2"} => {"a": "12"}
	//
	//	# Examples of merging objects containing lists of strings.
	//	{"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]}
	//
	// For a more complete example, suppose a streaming SQL query is
	// yielding a result set whose rows contain a single string
	// field. The following `PartialResultSet`s might be yielded:
	//
	//	{
	//	  "metadata": { ... }
	//	  "values": ["Hello", "W"]
	//	  "chunked_value": true
	//	  "resume_token": "Af65..."
	//	}
	//	{
	//	  "values": ["orl"]
	//	  "chunked_value": true
	//	  "resume_token": "Bqp2..."
	//	}
	//	{
	//	  "values": ["d"]
	//	  "resume_token": "Zx1B..."
	//	}
	//
	// This sequence of `PartialResultSet`s encodes two rows, one
	// containing the field value `"Hello"`, and a second containing the
	// field value `"World" = "W" + "orl" + "d"`.
	Values []*structpb.Value `protobuf:"bytes,2,rep,name=values,proto3" json:"values,omitempty"`
