Are generic enums completely abstract?
When using `Result` or `Option` to get a value, the value is wrapped in a `Ok` or `Some`. For example, with pattern matching to get a `Result`:
let var: Json = match serde_json::from_str(&my_string) {
Ok(a) => a,
Err(e) => return e,
};
Will there be any representation of the `Ok`, `Err`, `Some`, or `None` in the machine code of the compiled program, or are they completely abstract mechanisms within the language?
