| // 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. |
