rustHow to iterate directory recursively in Rust

Iterating a directory recursively in Rust can be done using the WalkDir crate. It provides an iterator over the entries of a directory and its subdirectories.

Example code

use walkdir::WalkDir;

for entry in WalkDir::new("/path/to/dir") {
    let entry = entry.unwrap();
    println!("{}", entry.path().display());
}

Output example

/path/to/dir
/path/to/dir/subdir1
/path/to/dir/subdir1/file1
/path/to/dir/subdir1/file2
/path/to/dir/subdir2
/path/to/dir/subdir2/file3

Code explanation

• use walkdir::WalkDir;: imports the WalkDir crate.
• WalkDir::new("/path/to/dir"): creates a new WalkDir iterator over the entries of the directory at the given path.
• let entry = entry.unwrap(): unwraps the Result returned by the iterator.
• println!("{}", entry.path().display()): prints the path of the entry.
