I don’t think Rust will ever be officially supported. That said, GDExtension may improve to the point where the Rust extension can be fully viable to use.

Right now the extension isn’t fully there yet according to the godot-rust book. Some things like signals have limited support and there may be breaking changes in the future because GDExtension is still experimental.

gdext is only slowly being deloped since it only has 2 true core devs, despite having many contributors. That being said it’s already functional. It just doesn’t have all the features implemented yet. If you’re interested in using the project, and have rust knowledge consider contributing or supporting the project!
