I think `Array` needs a new method for this to work. In addition to `fn as_any(&self) -> &dyn Any` it should also provide `fn as_any_arc(self: &Arc<Self>) -> &Arc<dyn Any + Send + Sync + 'static>` (IIRC this is allowed by current Rust since `Arc` is special). From there you can [downcast the `Arc`](https://doc.rust-lang.org/std/sync/struct.Arc.html#method.downcast) and (if the user wants to) unwrap it (however for most cases it's OK to keep the concrete array type within the `Arc`). -- This is an automated message from the Apache Git Service.
