Crate rtv

This crate enables you to easily traverse a directory.

Use the Traverse struct to get all the files. You can either build them into a Vec or specify a callback function to call on every file.

You can also choose to ignore some errors or open files with custom permissions.

This function goes trough every file inside path/to/dir and its subdirectories and prints the content.

use rtv::Traverse;
use std::io::Read;

//  It is better to use String::with_capacity with the file's size to avoid multiple allocations.
let mut buff = String::new();

Traverse::new("path/to/dir").apply(|mut file, _| {
    file.read_to_string(&mut buff);
    println!("{}", buff);
});
