Rust 标准库 std::fs 提供了函数 remove_file() 用于删除文件。 remove_file() 函数的原型如下 pub fn remove_file<P: AsRef>(path: P) -> Result<()> 注意,删除可能会失败,即使返回结果为 OK,也有可能不会立即就删除。24.6.1 范例 下面的代码,我们使用 remove_file() 方法删除 data.txt。
let file = std::fs::File::create("data2.txt").expect("创建失败"); println!("文件创建成功:{:?}",file); 文件创建成功:File { fd: 4, path: "/Users/monster/Github/rust_edu/file26/data2.txt", read: false, write: true } 删除文件 使用remove_file()方法删除。 代码语言:txt 复制 fs...
例如,可以使用create_dir方法来创建一个目录,使用remove_file方法来删除一个文件等。 路径迭代和遍历:Path和PathBuf支持迭代器,可以使用iter方法返回路径的各个组成部分(例如目录名和文件名)。这样就可以方便地遍历路径中的每个组成部分,进行其他操作。 其他功能:除了上述功能,该文件还实现了其他一些辅助方法,如判断路径...
File struct:对于一个打开文件的引用。 std::io:IO操作。 BufRead trait:控制带buffer的读操作形式。 BufReader struct:带buffer的reader。 Write trait:控制写操作形式。 std::path :可实现跨平台的路径管理获取。 PathBuf struct:可修改路径,与String类似。 std::process :开辟子进程分担工作。 Command struct:...
