Best practice to handle Result/Option right now?

[stevefan1999-personal]

So I was thinking to build my own enum with ReprC using arbitrary enum discriminant but it seems like this isn't supported either. What should be replaced to work with 1. the Result type for error reporting? (while Option type are typically converted to T*)

I suspect we'll soon start supporting these (say, in a month or two), once the main revamp & cleanup of safer-ffi is done.

Until then, while not pretty, I guess you could try to setup something along the lines of:

#[derive_ReprC]
struct CResult<T : ReprC, Err: ReprC> {
    ok: Option<repr_c::Box<T>>,
    err: Option<repr_c::Box<Err>>,
}

else you could try to use an Error out parameter, as shown in: #113
