public sealed class StaticFuture : Future
`DexStaticFuture` represents a future that is resolved from the initial state.
Use this when you need to create a future for API reasons but already have the value or rejection at that point.
`DexStaticFuture` is used internally by functions like [ctor@Dex.Future.new_for_boolean] and similar.
