A Rust library for high performance directory walking using libc fts.

Documentation

Usage

[dependencies]
fts = "0.3.0"

Example

Use WalkDir for directory walking:

use std::path::Path;
use fts::walkdir::{WalkDir, WalkDirConf};

let path = Path::new( "." );
for p in WalkDir::new( WalkDirConf::new( path ) ) {
    println!( "{:?}", p.unwrap() );
}

Call fts_* function directly:

use std::ffi::CString;
use fts::ffi::{fts_open, fts_read, fts_close, FTS_LOGICAL};

let path    = CString::new( "." ).unwrap();
let paths   = vec![path.as_ptr(), std::ptr::null()];
let fts     = unsafe { fts_open ( paths.as_ptr(), FTS_LOGICAL, None ) };
let _ftsent = unsafe { fts_read ( fts ) };
let _       = unsafe { fts_close( fts ) };

Benchmark

A cargo bench result is the following. fts_walkdir is this library, readdir is std::fs:read_dir, walkdir is walkdir::WalkDir. a suffix _metadata means using call DirEntry::metadata().

test fts_walkdir          ... bench: 315,114,126 ns/iter (+/- 8,478,709)
test fts_walkdir_metadata ... bench: 480,089,245 ns/iter (+/- 11,478,335)
