I don't know whether a private struct could work with xorm.

I'm not sure if you're meaning this as a comment, e.g. I didn't know that a private struct would work with xorm, or if you're trying to express doubt that this will work, e.g. I don't think a private struct will work with xorm.

It will work.

If you are given a pointer to a nonExportedStruct:

package someplace

type notExportedStruct {
   Exported string
}

func NewNotExported() *notExportedStruct {
  return &notExportedStruct{}
}

you can always create another copy of it using:

package main

import "someplace"

func main() {
  notExported := somplace.NewNotExported()

	val := reflect.ValueOf(notExported).Elem()
	typ := val.Type()

	newNotExportedVal := reflect.New(typ)
  newNotExportedVal.Elem().FieldByName("Exported").SetString("I have been set by reflection")

	fmt.Println(newNotExportedVal.Interface())
}

Which is what xorm does internally anyway.

Xorm doesn't need to know or be able to cast to the non-exported type - it just uses reflection to look across the exported fields which will always work or casts to interfaces it knows e.g. TableName. newNotExportedVal can be cast to an interface{} using the .Interface() function as normal.
