Support for trait objects

[segeljakt]

Hi again, I'm wondering, is it possible to use serde_state to serialize trait objects? I tried to use it together with serde_traitobject but it seems to require serde::Serialize. Is there some other way you know of to achieve this?

This is what serde_traitobject allows:

trait MyTrait: serde_traitobject::Serialize + serde_traitobject::Deserialize {
    fn my_method(&self);
}

#[derive(Serialize, Deserialize)]
struct Message {
    #[serde(with = "serde_traitobject")]
    message: Box<dyn MyTrait>,
}

You would have to use serde_traitojbect (or the same approach at least). The only other option I know is to smuggle state via thread locals to let you use any non-state serializers.
