How to extract a component from a path?

help

Is there a short (direct) way to get a folder instead of this multi line contraction:
(I am seeking last folder)

 let my_dir   : PathBuf ;
 for component in std::path::Path::new(& std::env::current_dir()?).components().rev() {
        my_dir  =  component ;
        break;   
 }

components() returns an iterator, just use Iterator::last():

let dirname = std::env::current_dir()?.components().last()?;

if the path is a file but you want to get the containing directory, use parent().

There is also path.file_name() which has slightly different semantics but might be suitable for your needs.

    let dir_path = std::env::current_dir()?;
    let dir_name = dir_path.file_name().unwrap();

(Note: Despite the name, this works fine for directory paths as well as “ordinary file” paths.)
