kitex工具如何支持protobuf struct

代码中引起protobuf的struct结构，kitex命令行生成文件时报错。
kitex_gen/userve/userve.pb.fast.go:444:49: cannot use &v (value of type *structpb.Struct) as fastpb.Reader value in argument to fastpb.ReadMessage: *structpb.Struct does not implement fastpb.Reader (missing method FastRead)
kitex_gen/userve/userve.pb.fast.go:790:62: cannot use v (variable of type *structpb.Struct) as fastpb.Writer value in argument to fastpb.WriteMessage: *structpb.Struct does not implement fastpb.Writer (missing method FastWrite)
kitex_gen/userve/userve.pb.fast.go:1106:42: cannot use v (variable of type *structpb.Struct) as fastpb.Sizer value in argument to fastpb.SizeMessage: *structpb.Struct does not implement fastpb.Sizer (missing method Size)
kitex_gen/userve/userve.pb.fast.go:1215:18: undefined: structpb.File_api_struct_proto

proto用法：
...
import "google/protobuf/struct.proto";
message GetUserDataResponse {
map<string, google.protobuf.Struct> data = 1;
}
...

fastPB现在生成的代码不支持 import google/protobuf 下的类型。生成命令里，多加一个 -no-fast-api 参数，应该就可以了

[hmldd]

-no-fast-api 不影响grpc的数据传输吧？

不影响
