pub struct Opaque<V> {
    pub content: V,
}

A view that bridges the gap between impl View and impl View<T>.

fn opaque_view() -> impl View {
    button(text!("I am a button!"))
}

fn data_view<T>() -> impl View<T> {
    opaque(opaque_view())
}

where V: View,

pub fn new(content: V) -> Opaque<V>

Create a new opaque view.
