Dowser

Dowser is a(nother) fast, multi-threaded, 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 and hidden directories are followed like any other, including across devices;
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.

Additionally, path deduping relies on Unix metadata; this library is not compatible with Windows;

Depending on your needs, those limitations could be bad, in which case something like Walkdir would make more sense.

Installation

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

[dependencies] dowser = "0.4.*"

Features

| Feature | Description | Default | | ------- | ----------- | ------- | | parking_lot_mutex | Use parking_lot::Mutex instead of std::sync::Mutex. | Y |

To use this feature, alter the Cargo.toml bit to read:

[dependencies.dowser] version = "0.4.*" features = [ "parking_lot_mutex" ]

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 use whatever Iterator methods you want.

```rust use dowser::Dowser; use std::os::unix::ffi::OsStrExt; use std::path::PathBuf;

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

// Return only Gzipped files using callback filter. let files: Vec:: = Dowser::default() .withpath("/usr/share/man") .filter(|p| p.extension().mapor( false, |e| e.asbytes().eqignoreasciicase(b"gz") ) ) .collect(); ```
