Protoc must have been run (with the --swipl_out= option and the resulting top-level _pb.pl file loaded. For more details, see the "protoc" section of the overview documentation.

Fails if the term isn't of an appropriate form or if the appropriate meta-data from protoc hasn't been loaded, or if a field name is incorrect (and therefore nothing in the meta-data matches it).

Arguments:

Term	- The Prolog form of the data, as nested dicts.
MessageType	- Fully qualified message name (from the .proto file's package and message). For example, if the package is google.protobuf and the message is FileDescriptorSet, then you would use '.google.protobuf.FileDescriptorSet' or 'google.protobuf.FileDescriptorSet'. If there's no package name, use e.g.: 'MyMessage or '.MyMessage'. You can see the packages by looking at protobufs:proto_meta_package(Pkg,File,_) and the message names and fields by protobufs:proto_meta_field_name('.google.protobuf.FileDescriptorSet', FieldNumber, FieldName, FqnName) (the initial '.' is not optional for these facts, only for the top-level name given to protobuf_serialize_to_codes/3).
WireCodes	- Wire format of the message, which can be output using format('~s', [WireCodes]).

Errors

- version_error(Module-Version) you need to recompile the Module with a newer version of protoc.

- existence_error if a field can't be found in the meta-data

bug

- map fields don't get special treatment (but see protobuf_map_pairs/3).
