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: standalone.rs
    path of file: ./repos/nih-plug/src/wrapper
    
    the code of the file until where you have to start completion: //! A standalone plugin target that directly connects to the system's audio and MIDI ports instead
//! of relying on a plugin host. This is mostly useful for quickly testing GUI changes.

use clap::{CommandFactory, FromArgMatches};

use self::backend::Backend;
use self:
    
fn run_wrapper<P: Plugin, B: Backend<P>>(backend: B, config: WrapperConfig) -> bool {
    let wrapper = match Wrapper::<P, _>::new(backend, config) {
        Ok(wrapper) => wrapper,
        Err(err) => {
            print_error(err);
            return false;
        }
    };

    // TODO: Add a repl while the application is running to interact with parameters
    match wrapper.run() {
        Ok(()) => true,
        Err(err) => {
            print_error(err);
            false
        }
    }
}
