Therefore, binary compatibility needs to be preserved\n  on changes to types.

+      "description": "`Any` contains an arbitrary serialized protocol buffer message along with a\nURL that describes the type of the serialized message.\n\nProtobuf library provides support to pack/unpack Any values in the form\nof utility functions or additional generated methods of the Any type.\n\nExample 1: Pack and unpack a message in C++.\n\n    Foo foo = ...;\n    Any any;\n    any.PackFrom(foo);\n    ...\n    if (any.UnpackTo(\u0026foo)) {\n      ...\n    }\n\nExample 2: Pack and unpack a message in Java.\n\n    Foo foo = ...;\n    Any any = Any.pack(foo);\n    ...\n    if (any.is(Foo.class)) {\n      foo = any.unpack(Foo.class);\n    }\n    // or ...\n    if (any.isSameTypeAs(Foo.getDefaultInstance())) {\n      foo = any.unpack(Foo.getDefaultInstance());\n    }\n\n Example 3: Pack and unpack a message in Python.\n\n    foo = Foo(...)\n    any = Any()\n    any.Pack(foo)\n    ...\n    if any.Is(Foo.DESCRIPTOR):\n      any.Unpack(foo)\n      ...\n\n Example 4: Pack and unpack a message in Go\n\n     foo := \u0026pb.Foo{...}\n     any, err := anypb.New(foo)\n     if err != nil {\n       ...\n     }\n     ...\n     foo := \u0026pb.Foo{}\n     if err := any.UnmarshalTo(foo); err != nil {\n       ...\n     }\n\nThe pack methods provided by protobuf library will by default use\n'type.googleapis.com/full.type.name' as the type URL and the unpack\nmethods only use the fully qualified type name after the last '/'\nin the type URL, for example \"foo.bar.com/x/y.z\" will yield type\nname \"y.z\".\n\nJSON\n====\nThe JSON representation of an `Any` value uses the regular\nrepresentation of the deserialized, embedded message, with an\nadditional field `@type` which contains the type URL. Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

+// Message that represents an arbitrary HTTP body. It should only be used for
