§Dowser
Dowser is a(nother) fast, recursive file-finding library for Rust, but 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;
- Directory paths are automatically crawled but not yielded;
§Example
Create a new instance using Dowser::default, then specify root paths to ignore and/or include with Dowser::without_path and Dowser::with_path, respectively.
From there, leverage your favorite Iterator trait methods to filter/collect the results.
use dowser::Dowser;
use std::path::PathBuf;
// Return all files under "/usr/share/man", and probably some from other places
// since some programs prefer to symlink their documentation.
let men: Vec::<PathBuf> = Dowser::default()
.with_path("/usr/share/man")
.collect();
// Same as above, but filtering paths as discovered so as to only keep the
// gzipped ones.
let men_gz: Vec::<PathBuf> = Dowser::default()
.with_path("/usr/share/man")
.filter(|p|
p.extension().is_some_and(|ext| ext.eq_ignore_ascii_case("gz"))
)
.collect();
