Enum fe_common::files::Utf8Component

pub enum Utf8Component<'a> {
    Prefix(Utf8PrefixComponent<'a>),
    RootDir,
    CurDir,
    ParentDir,
    Normal(&'a str),
}

A single component of a path.

A Utf8Component roughly corresponds to a substring between path separators (/ or \).

This enum is created by iterating over [Utf8Components], which in turn is created by the components method on Utf8Path.

Examples

use camino::{Utf8Component, Utf8Path};

let path = Utf8Path::new("/tmp/foo/bar.txt");
let components = path.components().collect::<Vec<_>>();
assert_eq!(&components, &[
    Utf8Component::RootDir,
    Utf8Component::Normal("tmp"),
    Utf8Component::Normal("foo"),
    Utf8Component::Normal("bar.txt"),
]);

Variants

Prefix(Utf8PrefixComponent<'a>)

A Windows path prefix, e.g., C: or \\server\share.

There is a large variety of prefix types, see [Utf8Prefix]’s documentation for more.

Does not occur on Unix.

RootDir

The root directory component, appears after any prefix and before anything else.

It represents a separator that designates that a path starts from root.

CurDir

A reference to the current directory, i.e., ..

ParentDir

A reference to the parent directory, i.e., ...

Normal(&'a str)

A normal component, e.g., a and b in a/b.

This variant is the most common one, it represents references to files or directories.

Implementations

impl<'a> Utf8Component<'a>

pub fn as_str(&self) -> &'a str

Extracts the underlying str slice.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("./tmp/foo/bar.txt");
let components: Vec<_> = path.components().map(|comp| comp.as_str()).collect();
assert_eq!(&components, &[".", "tmp", "foo", "bar.txt"]);

pub fn as_os_str(&self) -> &'a OsStr

Extracts the underlying OsStr slice.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("./tmp/foo/bar.txt");
let components: Vec<_> = path.components().map(|comp| comp.as_os_str()).collect();
assert_eq!(&components, &[".", "tmp", "foo", "bar.txt"]);

Trait Implementations

impl<'a> Clone for Utf8Component<'a>

fn clone(&self) -> Utf8Component<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Utf8Component<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Utf8Component<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Utf8Component<'a>

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for Utf8Component<'a>

fn cmp(&self, other: &Utf8Component<'a>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a> PartialEq for Utf8Component<'a>

fn eq(&self, other: &Utf8Component<'a>) -> 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.

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.
