walkdir provides efficient recursive directory traversal with customizable behavior. It handles symlinks, sorting, filtering, and error handling, and is the standard for directory walking in Rust.

Examples

Basic directory traversal:

use walkdir::WalkDir;

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

Filtering and controlling traversal:

use walkdir::WalkDir;

for entry in WalkDir::new(".")
    .max_depth(2)
    .into_iter()
    .filter_map(|e| e.ok())
    .filter(|e| e.path().extension().map_or(false, |ext| ext == "rs"))
{
    println!("Rust file: {}", entry.path().display());
}
