My question is: is this really dead code, or do I need to maintain raw_data for the memory to stay alive like I think I do? Yes, you need to maintain raw_data, or else crep will be invalidated. Do you absolutely need that crep field in SvmProb? I would instead suggest you add ...
must_use - on structs and enums, will warn if a value of this type isn’t used or assigned to a variable. You may also include an optional message by using #[must_use = “message”] which will be given alongside the warning. ...
