This has the advantage of not requiring you to declare all of your keys upfront, in cases where the set of keys might include arbitrary strings (for example, HTTP headers). The added bonus is that no one has to write any boilerplate code to make this happen. Any contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message. The any type represents an arbitrary protobuf message, allowing the client or server to encode non-predefined messages. Protobuf - Compound Data Types. prost uses a custom derive macro to handle encoding and decoding types, which means that if your existing Rust type is compatible with Protobuf types, you can serialize and deserialize it by adding the appropriate derive and field annotations.
