Struct std::path::Components

pub struct Components<'a> {
    // some fields omitted
}

The core iterator giving the components of a path.

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

Examples

fn main() { use std::path::Path; let path = Path::new("/tmp/foo/bar.txt"); for component in path.components() { println!("{:?}", component); } }

use std::path::Path;

let path = Path::new("/tmp/foo/bar.txt");

for component in path.components() {
    println!("{:?}", component);
}

Methods

impl<'a> Components<'a>

fn as_path(&self) -> &'a Path

Extracts a slice corresponding to the portion of the path remaining for iteration.

Examples

fn main() { use std::path::Path; let path = Path::new("/tmp/foo/bar.txt"); println!("{:?}", path.components().as_path()); }

use std::path::Path;

let path = Path::new("/tmp/foo/bar.txt");

println!("{:?}", path.components().as_path());

fn peek(&self) -> Option<Component<'a>>

Unstable (path_components_peek #27727)

Examine the next component without consuming it.
