# Objective #13320 added convenience methods for casting a `TypeInfo` into its respective variant: ```rust let info: &TypeInfo = <Vec<i32> as Typed>::type_info(); // We know `info` contains a `ListInfo`, so we can simply cast it: let list_info: &ListInfo = info.as_list().unwrap(); ``` This is especially helpful when you have already verified a type is a certain kind via `ReflectRef`, `ReflectMut`, `ReflectOwned`, or `ReflectKind`. As mentioned in that PR, though, it would be useful to add similar convenience methods to those types as well. ## Solution Added convenience casting methods to `ReflectRef`, `ReflectMut`, and `ReflectOwned`. With these methods, I was able to reduce our nesting in certain places throughout the crate. Additionally, I took this opportunity to move these types (and `ReflectKind`) to their own module to help clean up the `reflect` module. ## Testing You can test locally by running: ``` cargo test --package bevy_reflect --all-features ``` --- ## Showcase Convenience methods for casting `ReflectRef`, `ReflectMut`, and `ReflectOwned` into their respective variants has been added! This allows you to write cleaner code if you already know the kind of your reflected data: ```rust // BEFORE let ReflectRef::List(list) = list.reflect_ref() else { panic!("expected list"); }; // AFTER let list = list.reflect_ref().as_list().unwrap(); ``` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Pablo Reinhardt <126117294+pablo-lua@users.noreply.github.com> |
