> RAII doesn't make sense without initialization.

Rust has RAII and does not have constructors.

Rust mandates that every field in a user-defined type is initialized at once. How do you propose to retrofit that into C without "constructors"?

C has had designated initializers since C99, if you want you can initialise every struct field at once.

I encourage you to read (at least) this section of this blog before making simplistic suggestions: https://thephd.dev/just-put-raii-in-c-bro-please-bro-just-on...

How do you mandate initialization, handle copies, move objects, prevent double frees? What's RAII without any of that?
