m.XXX_unrecognized undefined

[jpfaria]

hello,

when I run my app, the follow error is returning:

JPFARIA-MacBook-Pro:server jpfaria$ go run main.go

gitlab.b2w/joao.faria/knativegrpcexample

../generated.pb.go:288:6: m.XXX_unrecognized undefined (type *User has no field or method XXX_unrecognized)

I had the same error and found golang/protobuf#594

Seeing as it now seems like the XXX_unrecognized field should be in the struct (ie, they would be in the struct if you used protoc to generate all of your Go code), I found that simply adding it to the struct worked for me. If you want to keep your structs clean of protobuf-specific fields, I found a not-so-bad workaround, of wrapping it in another struct, like this:

//proteus:generate
type PBPersonWrapper struct {
	Person
	XXX_unrecognized []byte
}

type Person struct {
	Name string
	Age  uint
}

It's not ideal, but it works.
