Rendering enum of templates

[rhelmot]

Let's say I have the following pattern:

#[derive(TemplateOnce)]
#[template(path = "index.stpl")]
struct Index {
    page: Page,
}

enum Page {
    Index(PageHome),
    Stream(PageStream),
}

#[derive(TemplateOnce)]
#[template(path = "pages/home.stpl")]
struct PageHome {
    ...
}

#[derive(TemplateOnce)]
#[template(path = "pages/stream.stpl")]
struct PageStream {
    ...
}

What can I write in the template such that I am able to render page? As far as I can tell, I can't implement TemplateOnce for Page since it has a sealed supertrait, and I can't implement Render for it since in order to render the child I would have to consume its value. I additionally can't change page to be dyn TemplateOnce since TemplateOnce is Sized.

What's the best way to dispatch to different templates?

I think this can be done with a macro, if you still need this I'm open to try to create one @rhelmot
