How to Pack/Unpack prost_types::Value and prost_types::Any?

[pionoor]

In the generated rust code from the proto file, I have a struct which has a field:

    pub data: ::core::option::Option<::prost_types::Value>,

generated from a protobuff field:

google.protobuf.Value data = 3;

I can't seem to find a way to pack some var into data which is type prost_types::Value.

There is another crate, prost-wkt, which provide pack/unpack funcs for Any. But it won't generate grpc server from proto. Is there a way to tell tonic_build to use prost-wkt-types instead of prost-types? I tried to do:

    tonic_build::configure()
        .extern_path(".google.protobuf.Any", "::prost_wkt_types::Any")
        .extern_path(".google.protobuf.Value", "::prost_wkt_types::Value")
        .compile(&["proto/grpc_service.proto"], &["proto"])
        .unwrap();

But it the generated file didn't compile.

Can you post the error you were getting when you made that config change?
