Trait TrimmablePath

pub trait TrimmablePath: AsRef<Path> {
    // Provided method
    fn trim_to_nth(&self, n: usize) -> Option<PathBuf> { ... }
}

A trait to easily obtain the last n parts of a path.

This trait is implemented for anything that implements AsRef<std::path::Path>, so you can use it on types like std::path::Path and std::path::PathBuf.

Examples

use std::path::Path;
use pathtrim::TrimmablePath;

let p = Path::new("/usr/local/bin/");
let trimmed = p.trim_to_nth(1).unwrap();
assert_eq!(trimmed.to_str().unwrap(), "bin");

Provided Methods

fn trim_to_nth(&self, n: usize) -> Option<PathBuf>

Returns a new PathBuf containing the last n components of the path, or None if there are not enough components in the path.

Examples

use std::path::Path;
use pathtrim::TrimmablePath;

let p = Path::new("/usr/local/bin/");
let trimmed = p.trim_to_nth(2).unwrap();
assert_eq!(trimmed.to_str().unwrap(), "local/bin");
