Object variants with non-public kind. #41
Description
I would expect this to work but I get an error: Error: undeclared field: 'kind' for type...
# moduleA.nim
type
Kinds* = enum A, B, C
Obj* = object
case kind: Kinds
of A: a: string
else: b: string
proc newObj*(kind: Kinds): Obj = Obj(kind:kind)
proc kind*(o: Obj): Kinds = o.kindimport flatty
import ./moduleA
let
a = newObj(B)
serialized = toFlatty(a)
writeFile("tmp.flat", serialized)
let
content = readFile("tmp.flat")
x = fromFlatty(content, Obj)Making the kind attribute public eliminates the error but I think that should not be necessary. It's also not ideal because then it's possible to change kind which I want to disallow:
# moduleA.nim
type
Kinds* = enum A, B, C
Obj* = object
case kind*: Kinds
of A: a: string
else: b: string
proc newObj*(kind: Kinds): Obj = Obj(kind:kind)import flatty
import ./moduleA
let
a = newObj(B)
serialized = toFlatty(a)
a.kind = C # Want to disallow this
writeFile("tmp.flat", serialized)
let
content = readFile("tmp.flat")
x = fromFlatty(content, Obj)

Thank you for your issue. I have been working on flatty for a bunch of things, and I think I have fixed this in this PR: #52
Feel free to re-open the issue if it still happens to you.
