Documentation

Info

A zip library for rust which supports reading and writing of simple ZIP files. Formerly hosted at https://github.com/zip-rs/zip2.

Supported compression formats:

  • stored (i.e. none)
  • deflate
  • deflate64 (decompression only)
  • bzip2
  • zstd
  • lzma (decompression only)
  • xz (decompression only)

Currently unsupported zip extensions:

  • Multi-disk

Features

The features available are:

  • aes-crypto: Enables decryption of files which were encrypted with AES. Supports AE-1 and AE-2 methods.
  • deflate: Enables compressing and decompressing an unspecified implementation (that may change in future versions) of the deflate compression algorithm, which is the default for zip files. Supports compression quality 1..=264.
  • deflate-flate2: Combine this with any flate2 feature flag that enables a back-end, to support deflate compression at quality 1..=9.
  • deflate-zopfli: Enables deflating files with the zopfli library (used when compression quality is 10..=264). This is the most effective deflate implementation available, but also among the slowest.
  • deflate64: Enables the deflate64 compression algorithm. Only decompression is supported.
  • lzma: Enables the LZMA compression algorithm. Only decompression is supported.
  • bzip2: Enables the BZip2 compression algorithm.
  • time: Enables features using the time crate.
  • chrono: Enables converting last-modified zip::DateTime to and from chrono::NaiveDateTime.
  • zstd: Enables the Zstandard compression algorithm.

By default aes-crypto, bzip2, deflate, deflate64, lzma, time and zstd are enabled.

The following feature flags are deprecated:

  • deflate-miniz: Use flate2's default backend for compression. Currently the same as deflate.

MSRV

Our current Minimum Supported Rust Version is 1.73. When adding features, we will follow these guidelines:

  • We will always support the latest four minor Rust versions. This gives you a 6 month window to upgrade your compiler.
  • Any change to the MSRV will be accompanied with a minor version bump.

Examples

See the examples directory for:

  • How to write a file to a zip.
  • How to write a directory of files to a zip (using walkdir).
  • How to extract a zip file.
  • How to extract a single file from a zip.
  • How to read a zip from the standard input.
  • How to append a directory to an existing archive

Fuzzing

Fuzzing support is through cargo fuzz. To install cargo fuzz:

cargo install cargo-fuzz

To list fuzz targets:

cargo +nightly fuzz list

To start fuzzing zip extraction:

cargo +nightly fuzz run fuzz_read

To start fuzzing zip creation:

cargo +nightly fuzz run fuzz_write
