如何检查给定路径是文件还是目录？

Question

I'm building a program that should be able to take both paths to files ( *.* ), and directories ( ./ , .. ). I want to be able to check if the path supplied is a file, or a directory.

You should use std::fs::metadata :

use std::fs::metadata;

fn main() {
    let md = metadata(".").unwrap();
    println!("is dir: {}", md.is_dir());
    println!("is file: {}", md.is_file());
}

Output:

is dir: true
is file: false
