FS Metadata

一个跨平台的简单封装，用于获取文件的元数据。

1. 以可读日期访问SystemTime。
2. 获取文件的权限。
3. 获取可读的文件大小。

函数

优先选择Struct版本。

pub fn file_created(path_str: &str) -> Result<String, String>

pub fn file_modified(path_str: &str) -> Result<String, String>

pub fn last_accessed(path_str: &str) -> Result<String, String>

结构体

struct FileMetadata {
    pub created: String,
    pub modified: String,
    pub accessed: String,
    pub is_file_read_only: bool,
    pub is_dir: bool,
    pub is_file: bool,
    pub is_readable: bool,
    pub is_writable: bool,
    pub is_executable: bool,
}

FileMetadata {
    fn new(path_str: &'static str) -> Result<Self, String>;
    fn readable(&self) -> bool;
    fn writable(&self) -> bool;
    fn executable(&self) -> bool;
    fn get_file_in_kilobytes(&self) -> f32;
    fn get_file_in_megabytes(&self) -> f32;
    fn get_file_in_gigabytes(&self) -> f32;
    fn get_file_in_terabytes(&self) -> f32;
}
