Trait amadeus::data::DowncastImpl

pub trait DowncastImpl<T> {
    fn downcast_impl(t: T) -> Result<Self, DowncastError>;
}

This trait lets one downcast a generic type like Value to a specific type like u64.

It exists, rather than for example using TryInto, due to coherence issues with downcasting to foreign types like Option<T>.
