`IteratorMethods`

[arcnmx]

A Rust wrapper around WpIteratorMethods could be somewhat useful:

• [ ] IteratorMethods wrapper type or trait
• [ ] safe WpIterator::with_impl(methods: IteratorMethods) or WpIterator::new(iter: impl IteratorMethods) or something
• [ ] impls for T: Iterator<impl ToValue>
  • [ ] figure out how to handle reset(), which isn't really doable without cloning the initial state or something
• [ ] WpIterator::empty() using IteratorMethods (stop using GPtrArray)
  • [ ] impl Default for WpIterator?
• [ ] ValueIterator<T>::new(iter: impl IteratorMethods<T>)
• [ ] ValueIterator::empty() (note: T: StaticType bound isn't necessary)
  • [ ] remove bound from Default impl as well
