|  | // `Any` contains an arbitrary serialized protocol buffer message along with a

 | ||
|  | //
 | ||
|  | // Protobuf library provides support to pack/unpack Any values in the form
 | ||
|  | // of utility functions or additional generated methods of the Any type.
 | ||
|  | //
 | ||
|  | // Example 1: Pack and unpack a message in C++.
 | ||
|  | //
 | ||
|  | //     Foo foo = ...;
 | ||
|  | //     Any any;
 | ||
|  | //     any.PackFrom(foo);
 | ||
|  | //     ...
 | ||
|  | //     if (any.UnpackTo(&foo)) {
 | ||
|  | //       ...
 | ||
|  | //     }
 | ||
|  | //
 | ||
|  | // Example 2: Pack and unpack a message in Java.
 | ||
|  | //
 | ||
|  | //     Foo foo = ...;
 | ||
|  | //     Any any = Any.pack(foo);
 | ||
|  | //     ...
 | ||
|  | //     if (any.is(Foo.class)) {
 | ||
|  | //       foo = any.unpack(Foo.class);
 | ||
|  | //     }
 | ||
|  | //
 | ||
|  | //  Example 3: Pack and unpack a message in Python.
 | ||
|  | //
 | ||
|  | //     foo = Foo(...)
 | ||
|  | //     any = Any()
 | ||
|  | //     any.Pack(foo)
 | ||
|  | //     ...
 | ||
|  | //     if any.Is(Foo.DESCRIPTOR):
 | ||
|  | //       any.Unpack(foo)
 | ||
|  | //       ...
 | ||
|  | //
 | ||
|  | //  Example 4: Pack and unpack a message in Go
 | ||
|  | //
 | ||
|  | //      foo := &pb.Foo{...}
 | ||
|  | //      any, err := anypb.New(foo)
 | ||
|  | //      if err != nil {
 | ||
|  | //        ...
 | ||
|  | //      }
 | ||
|  | //      ...
 | ||
|  | //      foo := &pb.Foo{}
 | ||
|  | //      if err := any.UnmarshalTo(foo); err != nil {
 | ||
|  | //        ...
 | ||
|  | //      }
 | ||
|  | //
 | ||
|  | // The pack methods provided by protobuf library will by default use
 | ||
|  | // 'type.googleapis.com/full.type.name' as the type URL and the unpack
 | ||
|  | // methods only use the fully qualified type name after the last '/'
 | ||
|  | // in the type URL, for example "foo.bar.com/x/y.z" will yield type
 | ||
|  | // name "y.z".
 | ||
|  | //
 | ||
|  | //
 | ||
|  | // JSON
 | ||
|  | // ====
 | ||
|  | // The JSON representation of an `Any` value uses the regular
 | ||
|  | // representation of the deserialized, embedded message, with an
 | ||
|  | // additional field `@type` which contains the type URL. Example:
 | ||
|  | //
 | ||
|  | //     package google.profile;
 | ||
|  | //     message Person {
 | ||
|  | //       string first_name = 1;
 | ||
|  | //       string last_name = 2;
 | ||
|  | //     }
 | ||
|  | //
 | ||
|  | //     {
 | ||
|  | //       "@type": "type.googleapis.com/google.profile.Person",
 | ||
|  | //       "firstName": <string>,
 | ||
|  | //       "lastName": <string>
 | ||
|  | //     }
 | ||
|  | //
 | ||
|  | // If the embedded message type is well-known and has a custom JSON
 | ||
|  | // representation, that representation will be embedded adding a field
 | ||
|  | // `value` which holds the custom JSON in addition to the `@type`
 | ||
|  | // field. Example (for message [google.protobuf.Duration][]):
 | ||
|  | //
 | ||
|  | //     {
 | ||
|  | //       "@type": "type.googleapis.com/google.protobuf.Duration",
 | ||
|  | //       "value": "1.212s"
 | ||
|  | //     }
 | ||
|  | //
 | ||
|  | message Any {
 | ||
|  |   // A URL/resource name that uniquely identifies the type of the serialized
 | ||
|  |   // protocol buffer message. This string must contain at least
 | ||
|  |   // one "/" character. The last segment of the URL's path must represent
 | ||
|  |   // the fully qualified name of the type (as in
 | ||
|  |   // `path/google.protobuf.Duration`). The name should be in a canonical form
 | ||
|  |   // (e.g., leading "." is not accepted).
 | ||
|  |   //
 | ||
|  |   // In practice, teams usually precompile into the binary all types that they
 | ||
|  |   // expect it to use in the context of Any. However, for URLs which use the
 | ||
|  |   // scheme `http`, `https`, or no scheme, one can optionally set up a type
 | ||
|  |   // server that maps type URLs to message definitions as follows:
 | ||
|  |   //
 | ||
|  |   // * If no scheme is provided, `https` is assumed.
 | ||
|  |   // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
 | ||
|  |   //   value in binary format, or produce an error.
 | ||
|  |   // * Applications are allowed to cache lookup results based on the
 | ||
|  |   //   URL, or have them precompiled into a binary to avoid any
 | ||
|  |   //   lookup. Therefore, binary compatibility needs to be preserved
 | ||
|  |   //   on changes to types. (Use versioned type names to manage
 | ||
|  |   //   breaking changes.)
 | ||
|  |   //
 | ||
|  |   // Note: this functionality is not currently available in the official
 | ||
|  |   // protobuf release, and it is not used for type URLs beginning with
 | ||
|  |   // type.googleapis.com.
 | ||
|  |   //
 | ||
|  |   // Schemes other than `http`, `https` (or the empty scheme) might be
 | ||
|  |   // used with implementation specific semantics.
 | ||
|  |   //
 | ||
|  |   string type_url = 1;
 | ||
|  | 
 | ||
|  |   // Must be a valid serialized protocol buffer of the above specified type.
 | ||
|  |   bytes value = 2;
