# Objective Relevant issue: #4474 Currently glam types implement Reflect as a value, which is problematic for reflection, making scripting/editor work much more difficult. This PR re-implements them as structs. ## Solution Added a new proc macro, `impl_reflect_struct`, which replaces `impl_reflect_value` and `impl_from_reflect_value` for glam types. This macro could also be used for other types, but I don't know of any that would require it. It's specifically useful for foreign types that cannot derive Reflect normally. --- ## Changelog ### Added - `impl_reflect_struct` proc macro ### Changed - Glam reflect impls have been replaced with `impl_reflect_struct` - from_reflect's `impl_struct` altered to take an optional custom constructor, allowing non-default non-constructible foreign types to use it - Calls to `impl_struct` altered to conform to new signature - Altered glam types (All vec/mat combinations) have a different serialization structure, as they are reflected differently now. ## Migration Guide This will break altered glam types serialized to RON scenes, as they will expect to be serialized/deserialized as structs rather than values now. A future PR to add custom serialization for non-value types is likely on the way to restore previous behavior. Additionally, calls to `impl_struct` must add a `None` parameter to the end of the call to restore previous behavior. Co-authored-by: PROMETHIA-27 <42193387+PROMETHIA-27@users.noreply.github.com> |
