How can I list files of a directory in Rust?

Question

How can I list all the files of a directory in Rust? I am looking for the equivalent of the following Python code.

files = os.listdir(\'./\')

This can be done with glob. Try this on the playground:

extern crate glob;
use glob::glob;
fn main() {
    for e in glob("../*").expect("Failed to read glob pattern") {
        println!("{}", e.unwrap().display());
    }
}

You may see the source.

And for walking directories recursively, you can use the walkdir crate (Playground):

extern crate walkdir;
use walkdir::WalkDir;
fn main() {
    for e in WalkDir::new(".").into_iter().filter_map(|e| e.ok()) {
        if e.metadata().unwrap().is_file() {
            println!("{}", e.path().display());
        }
    }
}
