对于Rust业务开发，该如何消除全局变量，采用依赖注入的方式构建应用呢？

struct AppContext {
    config: Config,
    database: Database,
    logger: Logger,
}

trait Dependency {
    fn get_dependency(&self) -> Box<dyn Dependency>;
}

impl Dependency for Config {
    fn get_dependency(&self) -> Box<dyn Dependency> {
        Box::new(self.clone())
    }
}

fn main() {
    let config = Config::new();
    let database = Database::new(&config);
    let logger = Logger::new(&config);
    let app_context = AppContext {
        config,
        database,
        logger,
    };
    run_app(app_context);
}

fn run_app(app_context: AppContext) {
    let config = app_context.config.get_dependency();
    let database = app_context.database.get_dependency();
    let logger = app_context.logger.get_dependency();
    // 使用依赖项执行应用程序逻辑
}
