merge_from is unimplemented

"fn merge_from(&mut self, _is: &mut ::protobuf::CodedInputStream) -> ::protobuf::ProtobufResult<()> {{ unimplemented!(); }}",

It looks like based on this line merge_from is unimplemented. I'm getting an error here in my code, but I do see an implementation here:

https://docs.rs/raft-proto/0.6.0/src/raft_proto/opt/rustwide/target/debug/build/raft-proto-e76d546c8402e8c8/out/protos/eraftpb.rs.html#2584-2603

How is this code being generated if it is in fact unimplemented?

Looks like maybe it's only unimplemented for prost?
