Expand description

文件系统类型

使用枚举避免魔数，同时保持与 Linux 魔数兼容

Variants§

§

Ext4 = 61_267

EXT2/3/4 文件系统 魔数来自：include/uapi/linux/magic.h

§

Unknown = 0

未知或不支持的文件系统

Implementations§

Source§

impl FileSystemType

Source

pub fn from_str(fs_type: &str) -> Self

从文件系统类型字符串获取枚举值

§示例
let fs_type = FileSystemType::from_str("ext4");
assert_eq!(fs_type, FileSystemType::Ext4);
Source

pub fn magic(self) -> i64

获取文件系统魔数

§返回值

返回 Linux 定义的文件系统魔数（i64）
