Can't serialize to session struct with enum member

[crimaniak]

I have a struct with enum like this:

struct UserModel // : BasicModel
{
	int id;
	string fullname;
	string email;
// ...
	enum systemId = 1;
}

Then I try to put it to session:

struct Registrator
{
	import vibe.http.server;
// ...
	enum LoggedUserVar = "loggedUser";
	enum LoggedVar = "logged";
// ...
	bool login(UserModel user)
	{
		session.set(LoggedUserVar, user);  // <--- problem is here
		session.set(LoggedVar, true);
		return true;
	}
// ...
}

Expected: compilation without errors In fact:

../../.dub/packages/vibe-d-0.7.30/vibe-d/source/vibe/internal/meta/traits.d(243,25): Error: argument 1 has no protection
../../.dub/packages/vibe-d-0.7.30/vibe-d/source/vibe/internal/meta/traits.d(159,19): Error: template instance vibe.internal.meta.traits.isPublicMember!(UserModel, "systemId") error instantiating

../../.dub/packages/vibe-d-0.7.30/vibe-d/source/vibe/data/serialization.d(1136,4):        instantiated from here: FilterSerializableFields!(UserModel, DefaultPolicy, "systemId")

source/vcm/bll/registrator.d(29,14):        instantiated from here: set!(UserModel)

enum systemId = 1; definitely is not struct field to set, so expected behavior is ignoring this symbol in (de)serialization process.

Workaround for current moment:

//	enum systemId = 1;

	@property static uint systemId()
	{
		return 1;
	}

For which compiler version does this happen and in which scope is the UserModel struct defined? I tried to make a reproduction case, but that worked without errors.

[crimaniak]

DMD64 D Compiler v2.071.1 UserModel defined in separate module vcm.bll.model.user and imported using import vcm.bll.model.user; Moving UserModel to the registrator module doesn't affect error. upd: Updated to v2.073.0, no change

@crimaniak : Is this bug still present ? I can't seem to reproduce either. If it is, could you make a simple, self-contained test case ?

[crimaniak]

It will be hard. I abandon D years ago because of a big amount of bugs, but I will try to find an example.
