1.0.0[][src]Enum std::path::Component

pub enum Component<'a> {
    Prefix(PrefixComponent<'a>),
    RootDir,
    CurDir,
    ParentDir,
    Normal(&'a OsStr),
}

A single component of a path.

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

This enum is created by iterating over Components, which in turn is created by the components method on Path.

Examples

use std::path::{Component, Path};

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

Variants

Prefix(PrefixComponent<'a>)

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

There is a large variety of prefix types, see Prefix'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 OsStr)

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.

Methods

impl<'a> Component<'a>[src]

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

Extracts the underlying OsStr slice.

Examples

use std::path::Path;

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