Is the anonymous struct (unnamed struct) still in progress?

Hello everyone,

Does anyone know the latest progress on anonymous structs (or unnamed structs)? I've looked through many posts, but they are all from a long time ago. I wonder if the development of the anonymous struct (or unnamed struct) feature is still ongoing?

Don’t assume that there is such a thing as “the anonymous struct feature” at all, if you haven't found evidence. There would need to be an accepted RFC in order to say that there is “the feature” as opposed to “an idea for a feature”. I found this closed RFC PR:

The comment when it was closed:

The general consensus was that this proposal does not fit our current priorities. Some lang team members did say it feels like a feature we should have in the long term (...), but it is not something we can justify investing project time on in the foreseeable future.

So, if you want this feature, the best way to help make it happen is to help implement already-accepted features (perhaps such as the related, accepted, unnamed_fields feature) so that there are fewer incomplete tasks, and the language and compiler teams have more attention free to consider more complex additions.
