The compress-tools crate aims to provide a convenient and easy to use set of methods which builds on top of libarchive exposing a small set of its functionalities.

Platform	Build Status
Linux - x86_64
macOS - aarch64
Windows - x86_64

You must have libarchive, 3.2.0 or newer, properly installed on your system in order to use this. If building on *nix and Windows GNU systems, pkg-config is used to locate the libarchive; on Windows MSVC, vcpkg will be used to locating the libarchive.

Typical install:

• Debian/Ubuntu: apt install libarchive-dev pkg-config
• macOS (Homebrew): brew install libarchive pkg-config (libarchive is keg-only; expose it via PKG_CONFIG_PATH="$(brew --prefix libarchive)/lib/pkgconfig")
• Windows MSVC: vcpkg install libarchive

The minimum supported Rust version is 1.82.

[dependencies]
compress-tools = "0.16"

To enable async support backed by tokio:

[dependencies]
compress-tools = { version = "0.16", features = ["tokio_support"] }

See Feature flags for the full list.

0.16.0 introduces a few breaking changes. See CHANGES.md for the complete list; the highlights are:

• Archive entry points now reject non-archive input. list_archive_files, list_archive_entries, uncompress_archive, uncompress_archive_file, and ArchiveIterator (and their _with_encoding / async variants) no longer treat arbitrary byte streams as a single-entry archive named data. If you relied on that behavior with the iterator, opt back in with ArchiveIteratorBuilder::raw_format(true). Raw compressed streams remain handled by uncompress_data.
• Async entry points require AsyncSeek. The async variants of list_archive_files, uncompress_archive, and uncompress_archive_file now bound the source on AsyncRead + AsyncSeek. Wrap tokio::fs::File via tokio_util::compat as needed.
• Error::Extraction changed shape. It now carries a details string and an optional io::Error reconstructed from archive_errno. Match arms using Error::Extraction(msg) should be rewritten as Error::Extraction { details, .. }.
• New Error::UnsupportedZipCompression variant. ZIP archives using Deflate64 (method 9) are now rejected up front instead of failing mid-extraction. Exhaustive match arms on Error need a new branch (or a catch-all).
• MSRV raised to 1.82.0 (was 1.65.0). Older toolchains will fail to build.

This crate is capable of extracting:

• compressed files
• archive files
• a single file from an archive

use compress_tools::*;
use std::fs::File;
use std::path::Path;

let mut source = File::open("tree.tar.gz")?;
let dest = Path::new("/tmp/dest");

uncompress_archive(&mut source, &dest, Ownership::Preserve)?;

use compress_tools::uncompress_archive_file;
use std::fs::File;

let mut source = File::open("tree.tar.gz")?;
let mut target = File::create("/tmp/README.md")?;

uncompress_archive_file(&mut source, &mut target, "tree/README.md")?;

use compress_tools::{ArchiveContents, ArchiveIteratorBuilder};
use std::fs::File;

let source = File::open("tree.tar.gz")?;
let iter = ArchiveIteratorBuilder::new(source).build()?;

for content in iter {
    match content {
        ArchiveContents::StartOfEntry(name, _stat) => println!("entry: {name}"),
        ArchiveContents::DataChunk(_bytes) => { /* stream the entry body */ }
        ArchiveContents::EndOfEntry => {}
        ArchiveContents::Err(e) => return Err(e.into()),
    }
}

use compress_tools::list_archive_entries;
use std::fs::File;

let mut source = File::open("tree.tar")?;
for entry in list_archive_entries(&mut source)? {
    println!("{}: {} bytes", entry.path, entry.size);
}

Requires the tokio_support feature.

use compress_tools::tokio_support::ArchiveIteratorBuilder;
use compress_tools::ArchiveContents;
use futures_util::StreamExt;
use tokio::fs::File;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let source = File::open("tree.tar.gz").await?;
    let mut iter = ArchiveIteratorBuilder::new(source).build();

    while let Some(content) = iter.next().await {
        if let ArchiveContents::StartOfEntry(name, _stat) = content {
            println!("entry: {name}");
        }
    }
    Ok(())
}

use compress_tools::{ArchiveIteratorBuilder, ArchivePassword};
use std::fs::File;

let source = File::open("secret.zip")?;
let iter = ArchiveIteratorBuilder::new(source)
    .with_password(ArchivePassword::new("<your password>")?)
    .build()?;

for _content in iter {
    // ...
}
