Lib.rs

This project is a 7z compressor/decompressor written in pure Rust.

This is a fork of the original, unmaintained sevenz-rust crate to continue the development and maintenance.

Supported Codecs & filters

(*) Require optional cargo feature.

Usage

[dependencies]
sevenz-rust2 = { version = "0.20" }

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

sevenz_rust2::decompress_file("data/sample.7z", "data/sample").expect("complete");

Decompress an encrypted 7z file

Use the helper function to encrypt and decompress source file "path/to/encrypted.7z" to destination path "data/sample":

sevenz_rust2::decompress_file_with_password("path/to/encrypted.7z", "data/sample", "password".into()).expect("complete");

Compression

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

sevenz_rust2::compress_to_path("examples/data/sample", "examples/data/sample.7z").expect("compress ok");

Compress with AES encryption

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

sevenz_rust2::compress_to_path_encrypted("examples/data/sample", "examples/data/sample.7z", "password".into()).expect("compress ok");

Advanced Usage

Solid compression

Solid archives can in theory provide better compression rates, but decompressing a file needs all previous data to also be decompressed.

use sevenz_rust2::*;

let mut writer = ArchiveWriter::create("dest.7z").expect("create writer ok");
writer.push_source_path("path/to/compress", | _ | true).expect("pack ok");
writer.finish().expect("compress ok");

Configure the compression methods

With encryption and lzma2 options:

use sevenz_rust2::*;

let mut writer = ArchiveWriter::create("dest.7z").expect("create writer ok");
writer.set_content_methods(vec![
    encoder_options::AesEncoderOptions::new("sevenz-rust".into()).into(),
    encoder_options::Lzma2Options::from_level(9).into(),
]);
writer.push_source_path("path/to/compress", | _ | true).expect("pack ok");
writer.finish().expect("compress ok");

WASM support

WASM is supported, but you can't use the default features. We provide a "default_wasm" feature that contains all default features with the needed changes to support WASM:

RUSTFLAGS='--cfg getrandom_backend="wasm_js"' cargo build --target wasm32-unknown-unknown --no-default-features --features=default_wasm
