How to get path.join in Rust?

Question

How do I write the path.join in Rust. I tried multiple examples but couldn't get it.

const exeDirectory = path.join(__dirname, '..', 'bin', 'openvpn.exe');
const processFile = path.join(__dirname, '..', '1');

I want to convert these lines of JS into Rust.

Answer 1

Use Path which has the .join method

Path::new("..").join("bin").join("openvpn.exe");

Answer 2

Another option is collecting an iterator of string into a PathBuf:

let path: PathBuf = ["..", "bin", "openvpn.exe"].iter().collect();

This is equivalent to creating a new PathBuf and calling .push() for each string in the iterator. To add multiple new components to an existing PathBuf, you can use the extend() method:

let mut path = PathBuf::from(dir_name);
path.extend(&["..", "bin", "openvpn.exe"]);
