Enum std::path::Component

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

A single component of a path.

See the module documentation for an in-depth explanation of components and their role in the API.

This enum is created from iterating over the path::Components struct.

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()),
]);

Variants

Prefix(PrefixComponent<'a>)

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

Does not occur on Unix.

RootDir

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

CurDir

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

ParentDir

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

Normal(&'a OsStr)

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