Struct linux_syscall_api::FilePath

pub struct FilePath(/* private fields */);

A struct to represent a file path, which will be canonicalized

Implementations

impl FilePath

pub fn new(path: &str) -> Result<FilePath, AxError>

创建一个 FilePath, 传入的 path 会被 canonicalize, 故可以是相对路径

pub fn path(&self) -> &str

获取路径

pub fn dir(&self) -> Result<&str, AxError>

获取所属目录

pub fn file(&self) -> Result<&str, AxError>

获取文件/目录名

pub fn is_root(&self) -> bool

返回是否是根目录

pub fn is_dir(&self) -> bool

返回是否是目录

pub fn is_file(&self) -> bool

返回是否是文件

pub fn equal_to(&self, other: &FilePath) -> bool

判断是否相同

pub fn start_with(&self, other: &FilePath) -> bool

判断是否start_with

pub fn end_with(&self, other: &FilePath) -> bool

判断是否end_with

Trait Implementations

impl Clone for FilePath

fn clone(&self) -> FilePath

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FilePath

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Ord for FilePath

fn cmp(&self, other: &FilePath) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FilePath

fn eq(&self, other: &FilePath) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FilePath

fn partial_cmp(&self, other: &FilePath) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
