How to delete all the files in a directory in Rust?

In rust there are many ways to delete all files in a directory, but before trying to delete them you should make sure none of these files is being opened or used by any program because there will be a lock on the file and that will cause a problem executing your application.

1) Delete file by delete complete directory and recreate it

Using this way it will delete the folder completely using fs::remove_dir_all and then recreate the same folder again using fs::create_dir

#![allow(unused)]

use std::fs;

fn main() {
    let path = "tmp/folderWithFiles";
    fs::remove_dir_all(path).unwrap();
    fs::create_dir(path).unwrap();
}

2) Delete file by delete iterating through them

Using this way it will delete the files one by one by getting all files using function read_dir()

use std::fs;
use std::io;
use std::path::Path;

fn remove_dir_contents<P: AsRef<Path>>(path: P) -> io::Result<()> {
    for entry in fs::read_dir(path)? {
        fs::remove_file(entry?.path())?;
    }
    Ok(())
}

fn main() {
    remove_dir_contents("tmp/folderWithFiles").unwrap();
}
