Struct std::path::Components1.0.0 [] [src]

pub struct Components<'a> { /* 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.

This struct is created by the path::Path::components method.

Examples

use std::path::Path;

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

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

Methods

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

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

Examples

use std::path::Path;

let mut components = Path::new("/tmp/foo/bar.txt").components();
components.next();
components.next();

assert_eq!(Path::new("foo/bar.txt"), components.as_path());Run
