// This file is an example and test case on handling the Any type in nanopb.
// The Any type is defined in Google-provided any.proto file:
// message Any {
//      string type_url = 1;
//      bytes value = 2;
// }
//
// The type_url field identifies the type of message, and the message data
// is inside the bytes field.
//
// The encoding follows the basic format of protobuf and doesn't require
// special support to handle. In this example, we just set maximum size for
// the type_url and value fields, and then call pb_decode() again on the value.
//
// This does result in unnecessarily copying the data around, so for larger
// values it is preferable to use callbacks on the fields instead.
