Dowser

Dowser is a(nother) fast, recursive file-finding library for Unix/Rust. It differs from Walkdir and kin in a number of ways:

• It is not limited to one root; any number of file and directory paths can be loaded and traversed en masse;
• Symlinks are followed by default, but can be disabled using Dowser::without_symlinks;
• Hidden paths and mount points are traversed like anything else;
• Matching file paths are canonicalized and deduped before yielding;

If those things sound nice, this library might be a good fit.

On the other hand, Dowser is optimized for file searching; the iterator crawls but does not yield directory paths, which could be bad if you need those too. Haha.

Installation

Add dowser to your dependencies in Cargo.toml, like:

[dependencies]
dowser = "0.16.*"

Example

All you need to do is chain Dowser::default with one or more of the following seed methods:

• Dowser::with_path / Dowser::with_paths
• Dowser::without_path / Dowser::without_paths

From there, you can apply any Iterator methods you want.

use dowser::Dowser;
use std::path::PathBuf;

// Return all files under "/usr/share/man".
let files1: Vec::<PathBuf> = Dowser::default()
    .with_path("/usr/share/man")
    .collect();

// Return only Gzipped files using callback filter.
let files1: Vec::<PathBuf> = Dowser::default()
    .with_path("/usr/share/man")
    .filter(|p|
        p.extension().is_some_and(|e| e.eq_ignore_ascii_case("gz"))
    )
    .collect();
