Learning Rust ATM and using bindgen on a C header. Just looked and it generates Rust enums from C enums. I'm not sure what the default behavior of bindgen is, but it seems there is option for constifying enums

--constified-enum <REGEX> Mark any enum whose name matches REGEX as a series of constants

--constified-enum-module <REGEX> Mark any enum whose name matches REGEX as a module of constants

IMO, saying bindgen avoids the issue presented in the article is not accurate.
