use std::path::PathBuf;

fn main() {
    let path = PathBuf::from("empty//dot/./parent/../");
    println!("base {:?}", path);
    println!("join(empty) {:?}", path.join(PathBuf::from("")));
    println!("join(dot) {:?}", path.join(PathBuf::from(".")));
    println!("join(./) {:?}", path.join(PathBuf::from("./")));

From what I gather, std::path seems to focus on being a low level API that can work on non-traditional systems. This means it cannot assume what is intended by extraneous/s,., or..`.

Yes, there is canonicalize but sometimes you need it done on relative paths when doing comparisons.

Python's pathlib automatically cleans up paths like this.
