通过系统文件保存和恢复状态和进度

示例

状态保存

let state_saver = StateSaver::new("state.txt");
        
state_saver.save(&1); 
assert_eq!(state_saver.state(), Some(1));

在应用程序重启后

let state_saver = StateSaver::new("state.txt");

assert_eq!(state_saver.state(), Some(1));

进度保存

let state_saver = ProgressSaver::new("state.txt");
        
state_saver.save(0, 1); 
assert_eq!(HashMap::from([(0, 1)]), progress_saver.state());

在应用程序重启后

let state_saver = ProgressSaver::new("state.txt");

assert_eq!(HashMap::from([(0, 1)]), progress_saver.state());
