I know I can implement some protocols to make JSON encoding work with structs and tuples.
However, decoding JSON would never produce the same input unless you included some meta data that specified which terms were atoms or structs etc.

I am seeing a few packages that do serialization/deserialization that can serialize structs, tuples, keyword lists, and atoms AND then unserialize them. The closest I think I found was php_serializer | Hex – it’s close, but the unserialize does not come back the way it went in.

I understand some things cannot be serialized (like captured functions I think?), but I think the structs and keyword lists can call be brought back. Does anyone know of a library that can unserialize this way?

So that:

input = %MyStruct{atom: :test, keyword: [a: "yes", b: "no"], tuple: {:ok, "yes"}}

result = input |> serialize() |> unserialize()

input == result

Thank you for any thoughts!
