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: theme.rs
    path of file: ./repos/termscp/src/ui/activities/setup/view
    
    the code of the file until where you have to start completion: //! ## SetupActivity
//!
//! `setup_activity` is the module which implements the Setup activity, which is the activity to
//! work on termscp configuration

// Locals
// Ext
use tuirealm::tui::layout::{Constraint, Direction, Layout};

use super::{components, Context, Id, IdCommon, IdTheme, SetupActivity, Theme, ViewLayout};

impl SetupActivity {
    // -- view

    
    fn load_titles(&mut self) {
        assert!(self

                Box::<components::AuthTitle>::default(),
                vec![]
