Hello,

I'm trying to use protobuf as an interface for our storage layer. Idea is to get RPC and execute some SQL/NoSQL code based on configuration. I'm trying to use gorm.io for SQL like databases.

I have proto file with message definition:

message Token {
    string uuid = 1;
...
}

This got generated into Go code:


type Token struct {
    Uuid                 string    `protobuf:"bytes,1,opt,name=uuid,proto3" json:"uuid,omitempty"`
...
}

How can I extend the formatting string for the fields and add some extra information, not related to protobufor or json, and add gorm: "primary_key" to the field, e.g.:

type Token struct {
    Uuid                 string    `protobuf:"bytes,1,opt,name=uuid,proto3" json:"uuid,omitempty" gorm:"primary_key"`
....
}
