Iterator that recursively scans and filters files from a directory.

Usage

Installation

Start using this library by running the following command in your cargo project directory.

cargo add dir-iterator

Read a Directory Recursively

use dir_iterator::*

fn main() {
    // create a new iterator starting in the current directory 
    DirIterator::new()
        // you will get this error if path was not found
        .expect("path not found")
        // while processing recursive dive multiple file system errors may occur.
        // flatten sorts them out
        .flatten()
        // print each file name
        .for_each(|e| println!("{:?}",e.file_name()));
}

Filter Result with Wildcards

use dir_iterator::*

fn main() {
    DirIterator::new()
        .expect("path not found")
        .flatten()
        // filter all files which have extension `txt`
        .filter(wildcard("*.txt"))
        .for_each(|e| println!("{:?}",e.file_name()));
}
