A 7z decompressor/compressor lib written in pure rust

This project is a 7z compressor/decompressor written in pure rust.
And it's very much inspired by the apache commons-compress project.

The LZMA/LZMA2 decoder and all filters code was ported from tukaani xz for java

Decompression

Supported codecs:

• BZIP2 (require feature 'bzip2')
• COPY
• LZMA
• LZMA2
• ZSTD (require feature 'zstd')

Supported filters:

• BCJ X86
• BCJ PPC
• BCJ IA64
• BCJ ARM
• BCJ ARM_THUMB
• BCJ SPARC
• DELTA
• BJC2

Usage

[dependencies]
sevenz-rust={version="0.2"}

Decompress source file "data/sample.7z" to dest path "data/sample"

sevenz_rust::decompress_file("data/sample.7z", "data/sample").expect("complete");

Decompress a encrypted 7z file

Add 'aes256' feature

[dependencies]
sevenz-rust={version="0.2", features=["aes256"]}

sevenz_rust::decompress_file_with_password("path/to/encrypted.7z", "path/to/output", "password".into()).expect("complete");

Multi-thread decompress

check examples/mt_decompress

Compression

Currently only support LZMA2 method.

[dependencies]
sevenz-rust={version="0.5.0", features=["compress"]}

Use the helper function to create a 7z file with source path.

sevenz_rust::compress_to_path("examples/data/sample", "examples/data/sample.7z").expect("compress ok");

With AES encryption

require version>=0.3.0

[dependencies]
sevenz-rust={version="0.5", features=["compress","aes256"]}

Use the helper function to create a 7z file with source path and password.

sevenz_rust::compress_to_path_encrypted("examples/data/sample", "examples/data/sample.7z", "password".into()).expect("compress ok");

Advance

[dependencies]
sevenz-rust={version="0.5.0", features=["compress","aes256"]}

Solid compression

use sevenz_rust::*;

let mut sz = SevenZWriter::create("dest.7z").expect("create writer ok");

sz.push_source_path("path/to/compress", |_| true).expect("pack ok");

sz.finish().expect("compress ok");

Compression methods

with encryption and lzma2 options

use sevenz_rust::*;

let mut sz = SevenZWriter::create("dest.7z").expect("create writer ok");
sz.set_content_methods(vec![
    sevenz_rust::AesEncoderOptions::new("sevenz-rust".into()).into(),
    lzma::LZMA2Options::with_preset(9).into(),
]);
sz.push_source_path("path/to/compress", |_| true).expect("pack ok");

sz.finish().expect("compress ok");
