Get the filesystem path of a file.
A simple extension trait for File that provides a single method path, which returns the path of a file.
Note: Not every file has a path. The path might be wrong for example after moving a file.
OS support: Linux, Mac, Windows
use std::fs::File;
use filepath::FilePath;
let mut file = File::create("foo.txt").unwrap();
println!("{:?}", file.path());
