Method RegisterStruct

go/fory/fory.go:273–298

RegisterStruct registers a struct type with a numeric ID for cross-language serialization. This is compatible with Java's fory.register(Class, int) method. type_ can be either a reflect.Type or an instance of the type typeID should be the user type ID in the range 0-0xfffffffe (0xffffffff is reserve

(type_ any, typeID uint32)

//

func (f *Fory) RegisterStruct(type_ any, typeID uint32) error {
	if err := validateUserTypeID(typeID); err != nil {
		return err
	}
	var t reflect.Type
	if rt, ok := type_.(reflect.Type); ok {
		t = rt
	} else {
		t = reflect.TypeOf(type_)
		if t.Kind() == reflect.Ptr {
			t = t.Elem()
		}
	}

	// Only struct types are supported via RegisterStruct
	// For enums, use RegisterEnum
	if t.Kind() != reflect.Struct {
		return fmt.Errorf("RegisterStruct only supports struct types; for enum types use RegisterEnum. Got: %v", t.Kind())
	}

	// Determine the internal type ID based on config
	var internalTypeID TypeId
	internalTypeID = f.typeResolver.structTypeID(t, false)

	return f.typeResolver.RegisterStruct(t, internalTypeID, typeID)
}

// RegisterUnion registers a union type with a numeric ID for cross-language serialization.
// type_ can be either a reflect.Type or an instance of the union type.
