+

+
+                        In practice, teams usually precompile into the binary

+
+                        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.)

+
+
+                    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"
