+
+// Package structpb contains generated types for google/protobuf/struct.proto.
+//
+// The messages (i.e., Value, Struct, and ListValue) defined in struct.proto are
+// used to represent arbitrary JSON. The Value message represents a JSON value,
+// the Struct message represents a JSON object, and the ListValue message
+// represents a JSON array. See https://json.org for more information.
+//
+// The Value, Struct, and ListValue types have generated MarshalJSON and
+// UnmarshalJSON methods such that they serialize JSON equivalent to what the
+// messages themselves represent. Use of these types with the
+// "google.golang.org/protobuf/encoding/protojson" package
+// ensures that they will be serialized as their JSON equivalent.
+//
+//
+// Conversion to and from a Go interface
+//
+// The standard Go "encoding/json" package has functionality to serialize
+// arbitrary types to a large degree. The Value.AsInterface, Struct.AsMap, and
+// ListValue.AsSlice methods can convert the protobuf message representation into
+// a form represented by interface{}, map[string]interface{}, and []interface{}.
+// This form can be used with other packages that operate on such data structures
+// and also directly with the standard json package.
+//
+// In order to convert the interface{}, map[string]interface{}, and []interface{}
+// forms back as Value, Struct, and ListValue messages, use the NewStruct,
+// NewList, and NewValue constructor functions.
+//
+//
+// Example usage
+//
+// Consider the following example JSON object:
+//
+//	{
+//		"firstName": "John",
+//		"lastName": "Smith",
+//		"isAlive": true,
+//		"age": 27,
+//		"address": {
+//			"streetAddress": "21 2nd Street",
+//			"city": "New York",
+//			"state": "NY",
+//			"postalCode": "10021-3100"
+//		},
+//		"phoneNumbers": [
+//			{
+//				"type": "home",
+//				"number": "212 555-1234"
+//			},
+//			{
+//				"type": "office",
+//				"number": "646 555-4567"
+//			}
+//		],
+//		"children": [],
+//		"spouse": null
+//	}
+//
+// To construct a Value message representing the above JSON object:
+//
+//	m, err := structpb.NewValue(map[string]interface{}{
+//		"firstName": "John",
+//		"lastName":  "Smith",
+//		"isAlive":   true,
+//		"age":       27,
+//		"address": map[string]interface{}{
+//			"streetAddress": "21 2nd Street",
+//			"city":          "New York",
+//			"state":         "NY",
+//			"postalCode":    "10021-3100",
+//		},
+//		"phoneNumbers": []interface{}{
+//			map[string]interface{}{
+//				"type":   "home",
+//				"number": "212 555-1234",
+//			},
+//			map[string]interface{}{
+//				"type":   "office",
+//				"number": "646 555-4567",
+//			},
+//		},
+//		"children": []interface{}{},
+//		"spouse":   nil,
