pathtrim

pathtrim is a simple, yet powerful Rust library that helps you obtain the last n parts of a filesystem path. It provides a seamless way to work with paths in a cross-platform manner, making it a great choice for projects that need to run on different systems like Unix, macOS, and Windows.

With pathtrim, you get a clean and intuitive API for handling path trimming, out-of-the-box support for different platforms, and the confidence that comes with strong safety guarantees, thanks to the use of Rust's features and ecosystem.

💡 Features

• Obtain the last n components of a path with just a line of code.
• Cross-platform: works seamlessly on Unix, macOS, and Windows.
• Built upon the powerful std::path module.
• Highly configurable, with a simple and easy-to-understand API.

🚀 Getting Started

Add this to your Cargo.toml:

[dependencies]
pathtrim = "0.2.0"

And then import the trait in the file where you want to use it:

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

Examples

Basic Usage

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

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

Different Platforms

Unix:

use std::path::Path;
use pathtrim::TrimmablePath;
let path = Path::new("/usr/local/bin/application");
let trimmed = path.trim_to_nth(3).unwrap();
assert_eq!(trimmed.to_str().unwrap(), "local/bin/application");

Windows:

use std::path::Path;
use pathtrim::TrimmablePath;
let path = Path::new(r"C:\Program Files\package\bin\application");
let trimmed = path.trim_to_nth(2).unwrap();
assert_eq!(trimmed.to_str().unwrap(), r"bin\application");

Edge Cases

use std::path::Path;
use pathtrim::TrimmablePath;
let path = Path::new("/");
let trimmed = path.trim_to_nth(1);
assert!(trimmed.is_none());
