Handle generic results

[SAtacker]

Currently we return -1 or some weird old C way of doing things and is non-standard. This is vague and unclear for any user. It is also unclear how we handle exceptions.

@SAtacker do you have any suggestion for what to do instead of returning -1
also for the exceptions handling are you referring to cpp side or rust side

[SAtacker]

Does Rust std:: use something like returning None type? Can we do something like that?
