You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: handler_arg_pass.rs
    path of file: ./repos/sdk-core/fsm/rustfsm_procmacro/tests/trybuild
    
    the code of the file until where you have to start completion: extern crate rustfsm_trait as rustfsm;

use rustfsm_procmacro::fsm;
use rustfsm_trait::Trans
    
fn main() {
    // state enum exists with both states
    let _ = SimpleState::One(One {});
    let _ = SimpleState::Two(Two {});
    // Avoid dead code warning
    let _ = SimpleEvents::A("yo".to_owned());
}
