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)
|
|
|
|
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 decompressing the deflate compression algorithm, which is the default for zip files.
|
|
* `deflate-zlib`: Enables deflating files with the `zlib` library (used when compression quality is 0..=9).
|
|
* `deflate-zlib-ng`: Enables deflating files with the `zlib-ng` library (used when compression quality is 0..=9).
|
|
This is the fastest `deflate` implementation available.
|
|
* `deflate-zopfli`: Enables deflating files with the `zopfli` library (used when compression quality is 10..=264). This
|
|
is the most effective `deflate` implementation available.
|
|
* `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](https://github.com/rust-lang-deprecated/time) crate.
|
|
* `chrono`: Enables converting last-modified `zip::DateTime` to and from `chrono::NaiveDateTime`.
|
|
* `zstd`: Enables the Zstandard compression algorithm.
|
|
|
|
By default `aes-crypto`, `deflate`, `deflate-zlib-ng`, `deflate-zopfli`, `bzip2`, `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 **1.70**. 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.
|
|
|

Fuzzing
|
|
-------
|
|
|
|
Fuzzing support is through [cargo fuzz](https://github.com/rust-fuzz/cargo-fuzz). To install cargo fuzz:
|
|
|
|
```bash
|
|
cargo install cargo-fuzz
|
|
```
|
|
|
|
To list fuzz targets:
|
|
|
|
```bash
|
|
cargo +nightly fuzz list
|
|
```
|
|
|
|
To start fuzzing zip extraction:
|
|
|
|
```bash
|
|
cargo +nightly fuzz run fuzz_read
|
|
```
|
|
|
|
To start fuzzing zip creation:
|
|
|
|
```bash
|
|
cargo +nightly fuzz run fuzz_write
|
|
```
