AddConversionByType for time.Time and timestamppb.Timestamp

[muradhajiyev]

I'm trying to convert from time.Time to timestamppb.Timestamp. This is the code I have written below but it doesn't work, and return such an error panic: reflect.Set: value of type time.Time is not assignable to type *timestamppb.Timestamp

Conversion:

	srcType := reflect.TypeOf((*time.Time)(nil)).Elem()
	targetType := reflect.TypeOf((**timestamppb.Timestamp)(nil)).Elem()
	model.AddConversionByType(srcType, targetType, func(in reflect.Value) (reflect.Value, error) {
		t := timestamppb.New(in.Interface().(time.Time))
		return reflect.ValueOf(&t), nil
	})

struct A {
 CreatedAt timeTime
}

struct B {
 CreatedAt *timestamppb.Timestamp
}

Is there anyone who can show me what I'm doing wrong here?

@muradhajiyev I can barely remember having written this conversion registration feature, but let me see if I can help :)

According to the docs I created I think the registration should look like this:

model.AddConversionByType((*time.Time)(nil), **timestamppb.Timestamp)(nil), func(in reflect.Value) (reflect.Value, error) {

So registering e.g. (*time.Time)(nil) instead of reflect.TypeOf((*time.Time)(nil)).Elem() may do the trick.
